your schools talent show will feature 16 solo acts and 2 ensemble acts. the show will last 102 minutes. the 8 solo performers judged best will give a repeat performance at a second 62 minute show. which will also feature the 2 ensemble acts. each solo act lasts x minutes and each ensemble act lasts y minutes.

-1   1/6.   you dont subtract the denominators

step-by-step explanation:

correct answer was 0.5

(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.
