Pls begging you help

Which is f(5) for the function –2x2 + 2x - 3?

Angles r and s are complementary. the measure of angle r is 31 degrees. which equation can be used to find angle s?

Will give let f(x)=2x and g(x)=[tex]2^{x}[/tex] graph the functions on the same coordinate plane. what are the solutions to the equation f(x)=g(x) ? enter your answers in the boxes x=[? ] or x=[? ]
