Answer: -17/28

Step-by-step explanation:

This is very easy.

We read f(x) as "a function of x"

Think of it as a machine. It takes in x, and gives us f(x) after doing some things to it.

f(x) = (x) × 4/7 + 9/4  ,

f(-5) = (-5) × 4/7 + 9/4

Let's work this out now!

= (-5) × 4/7 + 9/4

= -20/7 + 9/4

Now make into 1 fraction with common denominator

= -80/28 + 63/28

= -17/28
