Question

4)) function a
4)) function b
$y = 4x - 2$
which statement is true?
the y-value of function a when $x = -1$ is greater than the y-value of function b when $x = -1$.
the y-value of function a when $x = -1$ is less than the y-value of function b when $x = -1$.

Explanation:

Step1: Find y of Function A at x=-1

Locate $x=-1$ on the graph, the corresponding $y$-value is $-3$.

Step2: Find y of Function B at x=-1

Substitute $x=-1$ into $y=4x-2$:
$y=4(-1)-2=-4-2=-6$

Step3: Compare the two y-values

$-3 > -6$, so Function A's y-value is greater.

Answer:

The y-value of Function A when x = -1 is greater than the y-value of Function B when x = -1.
