(d) h(15)
415
Question 5: The function g is such that g(x) = 19 - 4x

Question 6: The function his such that h(x) =
53 - 1

Answer 1

just sub in the numbers into the equation to replace the X ..

example for

a) h(7) : 44

Explanation:

h(7) : x^2 -5

sub in 7 into the equation to replace X

so you get

(7)^2 - 5

49-5

44
