WILL MARK BRAINLIEST DUE IN 20 MINUTES!! A quadratic equation can be written in the form y = a(x – 5)2 + k, where (h, k)
is the vertex of the parabola. This form can be used to determine the minimum y-
value of the related function. Which is the minimum y-value of
y = 5x2 – 20x + 24?

A: -20
B: 2
C: 4
D: 16
