What is the y-value of the vertex of the function f(x) = –(x + 8)(x – 14)?

Hopes this helps

 quadratic function is in the form f(x) = ax2 + bx + c. A quadratic ... Find the vertex point, axis of symmetry, x and y intercepts and graph. 1) F(x) = x2 + 2x - 3.
find the x-intercept, y-intercept, axis of symmetry, and vertex of these two problems: ... (x-4)(x-2) = 0 ... y= 8; you can see in any equation the y intercept is the numerical value ... The x-intercepts are at thevalues of x where the function equals 0.

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
