select all functions that have a y-intercept of (0,5).
f(x)=7(b)^x-2
f(x)=-3(b)^x-5
f(x)=5(b)^x-1
f(x)=-5(b)^x+10
f(x)=2(b)^x+5

Step-by-step explanation:

we know that

The y-intercept is the value of y when the value of x is equal to zero

Verify each case

case 1) we have

so

For x=0

therefore

The function has a y-intercept of (0,5)

case 2) we have

so

For x=0

therefore

The function does not have a y-intercept of (0,5)

case 3) we have

so

For x=0

therefore

The function does not have a y-intercept of (0,5)

case 4) we have

so

For x=0

therefore

The function has a y-intercept of (0,5)

case 5) we have

so

For x=0

therefore

The function does not have a y-intercept of (0,5)
