Answer:

y=2x+4 or f(x)=2x+4

Step-by-step explanation:

f(0)=4 is (0,4) and f(2)=8 is (2,8)

first, find the slope using the equation y2-y1/x2-x1

8-4/2-0

4/2

2

now, take one of the points, and put it into the equation y2-y1=m(x-x1) (m is slope)

take (0,4) for example

y-4=2(x-0)

y-4=2x

y=2x+4

y=f(x)

so, substitute as

f(x)=2x+4

hope this helps!
