What function equation is represented by the graph? a. f(x)=4x+4 b. f(x)=4x+5 c. f(x)=3x+5 d. f(x)=3x+4

D. f(x)=3^x+4

Step-by-step explanation:

The graph crosses the y axis at 5 so the y intercept is 5

Anything to the zero power is 1

A. f(0)=4^0+4  = 1+4 =5

B. f(0)=4^0+5 =1+5 =6

C. f(0)=3^0+5 =1+5 =6

D. f(0)=3^0+4=1+5 =5

We can eliminate choices b and c

A. f(x)=4^x+4

D. f(x)=3^x+4

Let x = 2, y = is between 12 and 14

A. f(2)=4^2+4=16+4 =20

D. f(2)=3^2+4=9+4 = 13

So A is eliminated

D. f(x)=3^x+4

Step-by-step explanation:

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
