Find the equation of the tangent line to f(x)=x^2-2x+2 at x=4

Which is the graph of the function y=2(4)^x

Given ab and cb are tangents of p, and m =10°. what is the measure of abp?

Gabriel determined that his total cost would be represented by 2.5x + 2y – 2. his sister states that the expression should be x + x + 0.5x + y + y – 2. who is correct? explain.
