F(x)=x^2-3x. what is the value of f(-8).
-i need with the first step-

This is super easy simply plug -8 into all the x's 

F(x)=x^2-3x.
-8^2 - 3(-8) 
= 64 - 24 
= 40

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
