Question

If f(x) = x + 4 and g(x) = 2x - 3, find (g - f)(2).

Answer 1

(g - f)(2) is the same as g(2) - f(2)

Answer 2

are you able to find the value of g(2) ?

Answer 3

u plug in 2 for x and then subtract the functions

Answer 4

f(2)= 2+4
g(2)= 2(2) -3

Answer 5

f(2)= 6
g(2) = 1

Answer 6

ur gonna have to subtract f from g so it's 1-6

Answer 7

1-6= -5
