Question

graph the function.
y = 10(0.4)^x
plot two points to graph the function.

Explanation:

Step1: Find y at x=0

Substitute $x=0$ into $y=10(0.4)^x$.
$y=10(0.4)^0 = 10\times1 = 10$
Point: $(0, 10)$

Step2: Find y at x=1

Substitute $x=1$ into $y=10(0.4)^x$.
$y=10(0.4)^1 = 10\times0.4 = 4$
Point: $(1, 4)$

Answer:

Plot the points $(0, 10)$ and $(1, 4)$, then draw the exponential decay curve passing through them.
