Answer:
The required y-value is -121.
Step-by-step explanation:
There are several ways in which we could approach this problem. From the two binomial factors (x + 8) and (x - 14), we know that the two roots are x = -8 and x = 14. The axis of symmetry is the vertical line x = 3. This value is halfway between x = -8 and x = 14.
Substituting x = 3 into f(x)= -(x+8)(x-14) results in f(3) = -(11)(-11) = -121.
The vertex is at (3, -121). The required y-value is -121.
if a < 0, then the parabola opens down . The vertex is the lowest or highest point (depending on direction) on the graph of a quadratic function. Basically you will find the x value of the vertex first and then just plug that value into the function to get the y or functional value of the vertex. :)
