Question

If  is the  after a vertical compression by , a shift left by 1, and a shift down by 4,

a) write an equation for :  =   

b) The slope of this line is:   

c) The vertical intercept of this line is: 

Answer 1

g(x)= (1/2)f(x+1) -4, that is, g(x)=(1/2)(x+1) - 4= (1/2)x -3.5; g(x)= mx +b

then slope is m=1/2 and vertical intercept is b=-3.5
