Mia has a bag that contains pineapple chews, lemon chews, and watermelon chews. She performs an experiment. Mia randomly removes a chew from the bag, records the result, and returns the chew to the bag. Mia performs the experiment 65 times. The results are shown below: A pineapple chew was selected 25 times. A lemon chew was selected 14 times. A watermelon chew was selected 26 times. Based on these results, express the probability that the next chew Mia removes from the bag will be pineapple chew as a fraction in simplest form.

answer: graphs are something you write or draw and equations are math problems

(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.
