Answer:

f=7/3

Step-by-step explanation:

from the figure it can be deduced that x=3 and

y=7

so: y=f(x) → 7=f(3)

put f to the first member: 7=3f → 3f=7 → f=7/3

(I hope that's right)

Answer:

f(3) = 7

Step-by-step explanation:

locate x = 3 on the x- axis, then go vertically up to meet the line at (3, 7) , so

f(3) = 7
