Question

Let ​f(x)=x²+5x and ​g(x)=4x-3. Perform the composition or operation indicated.
(f/g)(-3)

Answer 1

9514 1404 393

Answer:

2/5

Explanation:

Put the numbers in the equations and do the arithmetic.

f(-3) = (-3)² +5(-3) = 9 -15 = -6

g(-3) = 4(-3) -3 = -12 -3 = -15

Then the composition is ...

(f/g)(-3) = f(-3)/g(-3) = -6/-15

(f/g)(-3) = 2/5
