Question

The graph of y = 4 – StartRoot 2 x EndRoot is shown.

On a coordinate plane, a curved line approaches the grid line at (3, 1.5) and ends at (0, 4).

Which statement about the graph is accurate?

The x-intercept of the graph is (4, 0).
The graph has no y-intercepts.
The maximum of the graph occurs at the y-intercept.
The minimum of the graph occurs at the x-intercept.

Answer 1

A

Explanation:

Answer 2

C (third option) The maximum of the graph occurs at the y-intercept.

Explanation:

We will use the process of elimination

It’s not option 1 because if you graph it using the graphing calculator you can see that the x intercept is 8,0 not 4,0

It’s not option 2 because you can see the y intercept is at 0,4 which means there is a y intercept

It’s not option 4 because the graph continues down even after the x intercept

Which leaves us with option 3

Hope this helps :)
