Answer:

Not a function

Step-by-step explanation:

There are two points in the set that have the same x-value or "input": (6,4) and (6,-4). This fails the vertical line test which means that one input will give two potential outputs. This cannot make a function.

What is the solutionto the equation √x^2+2x-25=√x+5

Answer:

Move

√ x +5 to the left side of the equation by subtracting it from both sides.

√ x 2 + 2 x − 25 − √ x + 5= 0

Graph each side of the equation. The solution is the x-value of the point of intersection.

x = 5

Answer:

$area = area \: of \: two \: semi \: circles + area \: of \: rectangle \\ = 2( \frac{1}{2} \pi {r}^{2} ) + (l \times w) \\ = 2( \frac{1}{2} \times 3.14 \times { (\frac{18}{2}) }^{2} ) + (18 \times 4.5) \\ = 254.47 + 81 \\ = 335.5 \: {ft}^{2}$
