If EF = 7x +11, FG = 34, and EG = 157, find the value of x. The drawing is not to scale. E. F. G.
A. X = 67
B. x = 18
C. r= 112
D. x = 16

the answer is 48m^2!

step-by-step explanation:

(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.

answer is b
