Question

Evaluate f(x)=0.7x+3.2 

for f(z)

Answer 1

Linette, assuming you are giving us all the information provided, you simply replace every x with z.

 

f(z) = 0.7z + 3.2

 

Basically, you substitute whatever was in the parentheses with whatever is there now.

 

For example, f(3) = 0.7(3) + 3.2 = 2.1 + 3.2 = 5.3

 

Hope this helps!
