Find the domain of the function f(x)= x to the power of 2 over 1 - x^2

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line?

Analyze the graph of the cube root function shown on the right to determine the transformations of the parent function. then, determine the values of a, h, and k in the general equation.

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
