how about I do number 15 and you do the rest
:
We just need to plug in the value of x which is given into every place x occurs in the function
:
15)15) f(x) = + 4
a. f(5) =
b. f(–7) =
c. f(0) =
:
a)f(5)=+4=9........see where I highlighted it that is where
:
I plugged in the given value of 5 into x+4
:
b)f(-7)=+4=-3
:
c)f(0)=+4=4
do the same thing for problem 16 and 17
:
remember in 17 there is an x squared and and x term....put the values in ALL occurences of x
