1. ## Functins....

1) if "f" is a decreasing function and f(5)=7, is f(0) less than, equal to or greater than 7?

2) If (3,-6) are coordinates of a point on the graphe of y=f(x), give the coordinates of a point on the graph of y=f(x)-4

3) the distance traveled by a ball rolling down a ramp is given by s(t)=3.5t^2, where t is the time in seconds after the ball is released, and s(t) is measured in feet. A) Find the distance the ball has rolled in 1 second. B) Find the distance the ball has rolled in 1.5 seconds. C) Find the average velocity of the ball in the interval from 1 second to 1.5 seconds

Can someone pls help me with that?

Thank you guys.

a) You tell us, decreasing means that as x increases f(x) decreases, Now take the contrapositive of that statement
Show your work for the rest and we will help as much as possible
