5. Which quadratic function has an axis of symmetry of x = 2 and a maximum value of 4?
A) y=3(x + 2)2 - 4
B) y=-3(x + 2)2 + 4
C) y = 3(x - 2)2 - 4
D) y=-3(x - 2)2 + 4​


Sagot :

Answer:

D) y = -3(x - 2) + 4

Step-by-step explanation:

axis of symmetry of x = 2 must be y = a(x - 2) + k

maximum value of 4 must be y = a(x - h) + 4

so the equation must be y = a(x - 2) + 4

only option D satisfy this condition
