Find thc mcasures of the three angles of a triangle if the sum of the measures of the first
angle and twice the measure of the second angle equals the measure of the third angle, and if
four times the measure of the second angle is 15 degrees more than the measure of the third
angle

step-by-step explanation:

what are the

his answer is incorrect. i just used it, and it said it was incorrect. the answer is 0.

(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.
