Given the function f, find -f(a)

Question

-f(a) = 4x-5 / 9x+2

Answer 1

f(x) = (4x-5) / (9x+2)

f(a) = (4a-5) / (9a+2)

-f(a) = (5-4a) / (9a+2)

Answer 2

Hi Mel,

You're just going to make the function negative. In this case: - (4x-5)/(9x+2). The negative can stay there, distribute in the numerator, or distribute in the denominator.
