If p(x)=2x^2-3x+1 and r(x)=x^2-5x, find r(x^2)-p(x+1) urgent please asap and provide work thank you!

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?

Factor the expression using gcf 9b+45

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
