Question

Identify the x- and y-intercepts of f(x) and the x- and y-intercepts of g(x). f(x) =3x−1;g(x)=2f(x)−4

Answer 1

F(x)=3x-1 

y-intercept:
y=3(0)-1 
y=-1 

x-intercept: 
0=3x-1 
1=3x
1/3=x

g(x)=2f(x)-4 

y-intercept: 
y=2f(0)-4 
y=2(-1)-4 
y=-6 

x-intercept: 
0=2f(x)-4 
0=2(3x-1)-4 
0=6x-2-4 
0=6x-6 
0=x-1 
1=x 

Hope I helped :)
