Part 2: last few questions so much guys! : ,) (function notation and rules and evaluating functions)

Hey there again, Lunablum!

For the first one, you just need to replace the value of x for 5, and solve it.
So, f(5) =  (5 - 4(5))
4 * 5 = 20
f(5) =  (5-20)
f(5) =  (-15)
and  times -15 will give you a total of  when simplified will give you a value of -5

Question number 10
It's the same thing as the last one, replace the value of t for -1 and solve it
g(-1) = ( - 1) (-1+4)
g(-1) = (1 - 1) (-1 + 4)
g(-1) = (0) (3)
g(-1) = 0
So the answer should be 0

The first table was already answered on the previous question
The answer is -2

The last table, the answer should be y = x or f(x) = x because whenever x is equal to a number, the y, or f(x), value will be equal to the same number, nothing is added nor subtracted. It has a slope of 1.

Thank you for using .
See you soon!
