F(x) = - (x + 8)(x - 14)
The zeros (solutions) to the function are -8 and 14.
The vertex lies between these two values. Eleven is the 'x' value of the vertex. To find the y values, plug 11 into the function and solve for y.
f(11) = -(11+8)(11-14)
f(11) = -(19)(-3)
f(11)= - (-57)
f(11) = 57
Answer:
First graph
Step-by-step explanation:
First off, the graph opens up because <em>a</em><em> </em>is positive. Second, the parent function of the quadratic graph is and the greater the WHOLE NUMBERS [vertical stretch (<em>a</em>)] get, the slimmer the parabola gets, and the more you increase the DEGREE evenly [anything ending in 0, 2, 4, 6, and\or 8], the more flat, U-shaped the parabola becomes.

3x-11=x+23
-x -x
2x-11=23
+11 +11
2x=34
x=17
3(17)-11 17+23
=40 =40
explanation ;
you would equal them because they are congruent . & you substitute x for 17 in each equation to find out the degrees of both of the angles :)
