f(-1) = 3

Step-by-step explanation:

f(-1) means the value of y at x = -1.

So what's the value of y at x = 1?

First, focus on the graph and look at x = -1.

Next, see which y-value does graph pass through when x = -1.

Looks like the graph passes y = 3 when x = -1

Thus, f(-1) = 3

you need to show the graph

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
