Question

Find the domain, range, and intercepts of the function f(x)= 7x+11

Answer 1

F(x) =y
Y=7x+11
For x intercept y=0
0=7x+11
0-11=7x
-11/7=7x/7
X=1.57(1.57,0)
For y intercept x=0
Y=7(0)+11
Y=0+11
(0,11)
For domain
Y=7x+11 make y subject
Domain{all real numbers}
Ranges make x subject
Y=7x+11
Y-11=7x
Y-11/7=x
Range {all real numbers
