Just plug in each value into x.

For example, f(2) = 4(2) + 10 = 18. The other three immediately follow.

Hi,         

Process is completed by substituting value given for x

f(x) = 4x + 10

f(2) = 4*2 + 10 = 18

f(-3) = 4*-3 + 10 = -2

f(k) = 4*k + 10 = 4k + 10

f(k^2-1) = 4(k^2-1) + 10 = 4k^2 - 4 + 10 = 4k^2 + 6
