3) The graph of a quadratic function has the vertex (4, 2) and passes through the point (5,5). What
is the equation of the function?

The equation of the function is:

Solution:

The vertex form of equation is given as:

Where, (h, k) is the vertex

Given that, The graph of a quadratic function has the vertex (4, 2)

(h, k) = (4, 2)

Substitute in eqn

And passes through the point (5,5)

Substitute (x, y) = (5, 5) in above

Substitute a = 3 and (h, k) = (4, 2) in vertex form

Thus the equation of function is found

i dont know sorry

step-by-step explanation:

i believe the answer is c.
