Write an equation for the graph below, which represents an exponential function f with base 2 or 3, translated and/or reflected.

Step-by-step explanation:

The model for an exponencial function is:

'c' is the value of the asymptote, so we have c = 3.

To find the value of 'a', let's use the point (0,5):

Now, to find the value of 'b', let's use the point (1, 7):

So our function is:

Let's check if the point (-1, 4) is inside our function:

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
