The graph of a quadratic function has a vertex located at (7,-3) and passes through points (5,5) and (9,5). Which equation best

Serga [27]

Answer:

B) $f(x)=2(x-7)^2-3$ .

Step-by-step explanation:

The vertex form of the equation is given by $f(x)=a(x-h)^2+k$ .

We plug in the vertex to obtain:

$f(x)=a(x-7)^2-3$ .

Since the graph passes through (5,5) and (9,5), they must satisfy its equation.

$5=a(9-7)^2-3$ .

$5+3=4a$ .

$8=4a$

Divide both sides by 4.

$a=2$

Therefore the equation is:

$f(x)=2(x-7)^2-3$ .
