I think it's b but i'm not sure!
Answer:
the first option
Step-by-step explanation:
because x^3 is exponential while ab^2 is linear
Answer:
B. 19
Step-by-step explanation:
g(x) = x^2+3
Let x=4
g(4) = 4^2 +3
= 16+3
=19
Answer:
The "formula" for an exponential function is f(x) = a * bˣ where a is the initial value / y-intercept. Therefore, a = 4 so f(x) = 4 * bˣ. To solve for b, we can plug in the values x = 3 and f(x) = 500 which becomes:
500 = 4 * b³
125 = b³
b = 5 so the answer is f(x) = 4 · 5ˣ.
