The y intercept of this function is always (0, a).
This is because when we place 0 in for x (which is the only way it'll be on the y-axis, we get 'a' as a result. This is because of the rule that raising anything to the 0th power will result in the number 1 and multiplying anything by 1 gives us the same number. See the work below for the example.
F(x) = a*b^x
F(0) = a*b^0
F(0) = a*1
F(0) = a
And for an example with a random number, we'll use a = 5 and b = 3
F(x) = 5*3^x
F(0) = 5*3^0
F(0) = 5*1
F(0) = 5
No matter what a and b equal, the intercept will be the a value.

Answer:
4/9
Step-by-step explanation:
1 1/3 * 1/3 =
= (1 + 1/3) * 1/3
= (3/3 + 1/3) * 1/3
= 4/3 * 1/3
= 4/9
A.) f(-0.5) = 4(-0.5) = -2
b.) f(0) = 5 - 0 = 5
c.) f(4) = |4| = 4
