What is the y- intercept of the exponential function?
f(x) = -32 (2)^[x-3] + 3
y intercept = ?
Y-intercept occurs where x = 0
Substitute x=0 in to the equation to find the y-intercept value....
-32 (2) ^(x - 3) + 3
Let x = 0
-32 (2)^(0 - 3) + 3
-32 (2)^(-3) + 3
-32 / (2)^3 + 3
-32 / 8 + 3
-4 + 3 =
-1 = y intercept
