Which of the following options best describes the function graphed below? A graph shows a curve that starts at the origin and go

Tamiku [17]

It's an increasing nonlinear. Exponential functions are graphed in basically any shape besides a line. This is an exponential function, therefore it is classified as nonlinear. By looking at the slope, from left to right, we can see that it is increasing, thus providing an answer that this is an increasing nonlinear function.

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:

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