The graph of a function in the form f(x) a(x - h)2 +k is shown. Use the graph to find an equation for f(x).
seropon [69]
O.K.

(h; k) are the coordinates of the vertex.

On the graph are (3; 4), therefore we have:

f(x)=a(x-3)^2+4

We have the x-intercept (1; 0) → x = 1; y = 0.
Substitute them in the equation:

0=a(1-3)^2+4\\\\0=a(-2)^2+4\\\\4a+4=0\ \ \ |-4\\\\4a=-4\ \ \ \ |:4\\\\a=-1

so. We have the answer:

\boxed{f(x)=-(x-3)^2+4}
