A number raised to power zero = 1
f(x)=7(b)^x-2
when x = 0
f(0) = 7- 2 = 5
f(x)=-3(b)^x-5
when x = 0
f(0) = -3 -5 = -8
f(x)=5(b)^x-1
when x = 0
f(0) = 5 - 1 = 4
f(x)=-5(b)^x+10
when x = 0
f(0) = -5 + 10 = 5
f(x)=2(b)^x+5
when x = 0
f(0) = 2 + 5 = 7
f(x)=7(b)^x-2
when x = 0
f(0) = 7- 2 = 5
f(x)=-3(b)^x-5
when x = 0
f(0) = -3 -5 = -8
f(x)=5(b)^x-1
when x = 0
f(0) = 5 - 1 = 4
f(x)=-5(b)^x+10
when x = 0
f(0) = -5 + 10 = 5
f(x)=2(b)^x+5
when x = 0
f(0) = 2 + 5 = 7
The two functions that have y-intercept of (0, 5) are:
f(x)=7(b)^x-2
f(x)=-5(b)^x+10

Answer:
Step-by-step explanation:
A number raised to power zero = 1
f(x)=7(b)^x-2
when x = 0
f(0) = 7- 2 = 5
f(x)=-3(b)^x-5
when x = 0
f(0) = -3 -5 = -8
f(x)=5(b)^x-1
when x = 0
f(0) = 5 - 1 = 4
f(x)=-5(b)^x+10
when x = 0
f(0) = -5 + 10 = 5
f(x)=2(b)^x+5
when x = 0
f(0) = 2 + 5 = 7
The two functions that have y-intercept of (0, 5) are:
f(x)=7(b)^x-2
f(x)=-5(b)^x+10
