Question

For the given functions f and g, find the requested function. Please show all of your work.
f(x)=5x^2+1;g(x)=5x^2+3 find f•g

Answer 1

I suppose that by that dot, you don't mean multiplication, but actually composition. All that means is that you plug the equation for g into x into the equation for f. Thus, the answer would be \[f\circ g=5(5x^2+3)^2+1\] You can finish the simplification.
