Math Square root functions

Question

Fill in the missing values in the table of values for this function.

	x-value	y-value
Starting point
x-intercept		0
y-intercept	0
Additional point	20

please solve the question and put it in the boxes.

Answer 1

	x-value	y-value
Starting point: (-16,2)	-16	2
x-intercept: (-12,0)	-12	0
y-intercept: (0,-2)	0	-2
Additional point	20	-4

To find starting point: Note that you can't have a negative number less than 0 under the sqrt sign. So, the smallest number x could be is -16. When you plug -16 in for x, you get 2 for y.

To find x intercept, let y (or f(x)) = 0. If you do that, you can an x of -12.

To find y intercept, let x = 0. When you do, you get y (i.e. f(x)) of = -2.

For the additional point, plug in 20 for x, and you get a y (i.e. f(x)) of -4.
