John uses a 25N force to push a boulder off a cliff that is 312m tall. What is the work done on the boulder?

how is that middle school

step-by-step explanation:

10.4 inches

step-by-step explanation:

2x2x2.6

15.36 per mile

but forgot to round

i am pretty sure

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.
