Answer 1

Answer:

C

Step-by-step explanation:

The exponential function has standard form

y = a $b^{x}$

Use the 2 given points to find a and b

Using (3, 182.25) , then

182.25 = a b³ → (1)

Using (2, 202.5) , then

202.5 = ab² → (2)

Divide (1) by (2)

$\frac{ab^3}{ab^2}$ = $\frac{182.25}{202.5}$

b = 0.9

Substitute b = 0.9 into (1) and solve for a

182.25 = a (0.9)³ ( divide both sides by (0.9)³

a = $\frac{182.25}{(0.9)^3}$ = 250

Thus

f(x) = 250 × $(0.9)^{x}$ ← third option
