Question

complete the table of values for the functions $f(x) = -2x + 6$ and $g(x) = 2(x - 1)^2$. write your answers as whole numbers, decimals, or simplified fractions or mixed numbers. \

$$\begin{tabular}{|c|c|c|} \\hline $x$ & $f(x)$ & $g(x)$ \\\\ \\hline 0 & \\square & \\square \\\\ \\hline 1 & \\square & \\square \\\\ \\hline 2 & \\square & \\square \\\\ \\hline 3 & \\square & \\square \\\\ \\hline 4 & \\square & \\square \\\\ \\hline \\end{tabular}$$

based on the values in the table, where does the equation $f(x) = g(x)$ have a solution? between $x = 0$ and $x = 1$ $x = 1$ between $x = 1$ and $x = 2$ $x = 2$

Explanation:

Response
Part 1: Completing the table for \( f(x) = -2x + 6 \) and \( g(x) = 2(x - 1)^2 \)
For \( f(x) = -2x + 6 \):
  • When \( x = 0 \):

Step 1: Substitute \( x = 0 \) into \( f(x) \)

\( f(0) = -2(0) + 6 \)

Step 2: Simplify

\( f(0) = 0 + 6 = 6 \)

  • When \( x = 1 \):

Step 1: Substitute \( x = 1 \) into \( f(x) \)

\( f(1) = -2(1) + 6 \)

Step 2: Simplify

\( f(1) = -2 + 6 = 4 \)

  • When \( x = 2 \):

Step 1: Substitute \( x = 2 \) into \( f(x) \)

\( f(2) = -2(2) + 6 \)

Step 2: Simplify

\( f(2) = -4 + 6 = 2 \)

  • When \( x = 3 \):

Step 1: Substitute \( x = 3 \) into \( f(x) \)

\( f(3) = -2(3) + 6 \)

Step 2: Simplify

\( f(3) = -6 + 6 = 0 \)

  • When \( x = 4 \):

Step 1: Substitute \( x = 4 \) into \( f(x) \)

\( f(4) = -2(4) + 6 \)

Step 2: Simplify

\( f(4) = -8 + 6 = -2 \)

For \( g(x) = 2(x - 1)^2 \):
  • When \( x = 0 \):

Step 1: Substitute \( x = 0 \) into \( g(x) \)

\( g(0) = 2(0 - 1)^2 \)

Step 2: Simplify the exponent

\( g(0) = 2(-1)^2 = 2(1) = 2 \)

  • When \( x = 1 \):

Step 1: Substitute \( x = 1 \) into \( g(x) \)

\( g(1) = 2(1 - 1)^2 \)

Step 2: Simplify the exponent

\( g(1) = 2(0)^2 = 2(0) = 0 \)

  • When \( x = 2 \):

Step 1: Substitute \( x = 2 \) into \( g(x) \)

\( g(2) = 2(2 - 1)^2 \)

Step 2: Simplify the exponent

\( g(2) = 2(1)^2 = 2(1) = 2 \)

  • When \( x = 3 \):

Step 1: Substitute \( x = 3 \) into \( g(x) \)

\( g(3) = 2(3 - 1)^2 \)

Step 2: Simplify the exponent

\( g(3) = 2(2)^2 = 2(4) = 8 \)

  • When \( x = 4 \):

Step 1: Substitute \( x = 4 \) into \( g(x) \)

\( g(4) = 2(4 - 1)^2 \)

Step 2: Simplify the exponent

\( g(4) = 2(3)^2 = 2(9) = 18 \)

Part 2: Finding where \( f(x) = g(x) \)

We look for intervals where \( f(x) \) and \( g(x) \) cross (i.e., where \( f(x) \) and \( g(x) \) change from \( f(x) > g(x) \) to \( f(x) < g(x) \) or vice versa).

  • At \( x = 0 \): \( f(0) = 6 \), \( g(0) = 2 \) (so \( f(x) > g(x) \))
  • At \( x = 1 \): \( f(1) = 4 \), \( g(1) = 0 \) (so \( f(x) > g(x) \))
  • At \( x = 2 \): \( f(2) = 2 \), \( g(2) = 2 \) (Wait, actually, let's check the values again. Wait, at \( x=1 \), \( f(1)=4 \), \( g(1)=0 \); at \( x=2 \), \( f(2)=2 \), \( g(2)=2 \)? Wait, no, wait: \( g(2) = 2(2-1)^2 = 2(1) = 2 \), and \( f(2) = -2(2) +6 = 2 \). Wait, but let's check the interval between \( x=1 \) and \( x=2 \):

Wait, maybe I made a mistake. Wait, let's re-express the functions:

\( f(x) = -2x +6 \) (linear, decreasing)

\( g(x) = 2(x-1)^2 \) (parabola opening upwards, vertex at \( (1, 0) \))

At \( x=1 \): \( f(1)=4 \), \( g(1)=0 \) (so \( f > g \))

At \( x=2 \): \( f(2)=2 \), \( g(2)=2 \) (so \( f = g \) at \( x=2 \)? Wait, but the options include "between \( x=1 \) and \( x=2 \)" or \( x=2 \). Wait, let's check the table again:

Wait, when \( x=1 \): \( f(1)=4 \), \( g(1)=0 \)

When \( x=2 \): \( f(2)=2 \), \( g(2)=2 \)

Wait, but the problem's options: "between \( x=0 \) and \( x=1 \)", "between \( x=1 \) and \( x=2 \)", "x=1", "x=2".

Wait, but let's check the values:

At \( x=1 \): \( f(1)=4 \), \( g(1)=0 \) (f > g)

At \( x=2 \): \( f(2)=2 \), \( g(2)=2 \) (f = g)

Wait, but maybe I miscalculated \( g(2) \). Wait, \( g(2) = 2(2-1)^2 = 2(1) = 2 \), and \( f(2…

Answer:

s:

Table Completion:
  • \( x=0 \): \( f(0)=6 \), \( g(0)=2 \)
  • \( x=1 \): \( f(1)=4 \), \( g(1)=0 \)
  • \( x=2 \): \( f(2)=2 \), \( g(2)=2 \)
  • \( x=3 \): \( f(3)=0 \), \( g(3)=8 \)
  • \( x=4 \): \( f(4)=-2 \), \( g(4)=18 \)
Solution to \( f(x) = g(x) \):

\( x = 2 \) (or between \( x=1 \) and \( x=2 \), but since at \( x=2 \) they are equal, the answer is \( x=2 \))
