Question

Consider the exponential function f(x) = 5(2) ^x

f(2)=
f(0)=
f(-1)=

what is the functions y-intercept?

Answer 1

Explanation:

The base is the number being raised to a power: (5/4).

The function is defined for all values of x, so the domain is (-∞, ∞).

The function given in this problem statement only has one value. That is the entirety of its range: [3(5/4)^3, 3(5/4)^3].

_____

Usually, an exponential function will have a range from 0 to infinity, not including either: (0, ∞). For that to be the case, we expect to see x in the exponent somewhere.
