What is the area...?

Given f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)

What is the slope of the line that contains the points (-2,1) and (0,-3)

Need match the functions with correct transformation. f(x) = -3x f(x) = |x-1|+3 f(x) = √(x+3) 1/2x² f(x) = (x+1)²-3 4|x| 1. compress by a factor of 1/2 2. stretch by a factor of 4 3. shift to the left 3 4. shift to the left 1 5. shift up 3 6. reflection
