What makes this equation an exponential function? y=6x+4

pretty sure its because it has an x, a y, and a variable!

Step-by-step explanation:

it has variables

Step-by-step explanation:

Definition: "Exponential functions have the form f(x) = bx, where b > 0 and b ≠ 1. Just as in any exponential expression, b is called the base and x is called the exponent."

That's the definition I found online.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
