Q:

Match the pairs of values of f(x) and g(x) with the corresponding values of h(x) if h(x) = f(x) ÷ g(x). Tiles f(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 Pairs h(x) = x + 5 arrowBoth h(x) = x + 3 arrowBoth h(x) = x + 4 arrowBoth h(x) = x − 1 arrowBoth

Accepted Solution

A:
For this case we must solve each of the functions.
 We have then:

 f (x) = x2 - 9, and g (x) = x - 3
 h (x) = (x2 - 9) / (x - 3)
 h (x) = ((x-3) (x + 3)) / (x - 3)
 h (x) = x + 3

 f (x) = x2 - 4x + 3, and g (x) = x - 3
 h (x) = (x2 - 4x + 3) / (x - 3)
 h (x) = ((x-3) (x-1)) / (x - 3)
 h (x) = x-1

 f (x) = x2 + 4x - 5, and g (x) = x - 1
 h (x) = (x2 + 4x - 5) / (x - 1)
 h (x) = ((x + 5) (x-1)) / (x - 1)
 h (x) = x + 5

 f (x) = x2 - 16, and g (x) = x - 4
 h (x) = (x2 - 16) / (x - 4)
 h (x) = ((x-4) (x + 4)) / (x - 4)
 h (x) = x + 4
