1) which is a quadratic function? f(x) = 2x x 3f(x) = 0x2 – 4x 7f(x) = 5x2 – 4x 5f(x) = 3x3 2x 2

A quadratic equation is a polynomial function in which the order or the highest degree among all the terms is 2. In this case, among the given functions, the polynomial equation would have to be c. f(x) = 5x2 - 4x + 5. There are also other euqations like trinomial equations in which the order is equal to 3.

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
