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
