Step-by-step explanation:

It is 1 <span>The value of correlation is always between -1.0 and +1.0.
so i hope this helps out let me know how it goes !

All you have to do to solve this question is to plug in gx as any other number you would plug in to the f(x) to solve the equation.
So it would be
F(3x-8) = 3(3x-8)^2 - 5(3x-8) - 9
Then FOIL the terms in the binomial or the first term, then after expanding the first term, distribute the numbers into each term inside the bracket and then at the end gather like terms to simplify.
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
