Annie wants to raise a pig for the county fair. The figure below is a diagram of what the pig pen will look like in order to fit
on the side of Annie’s house. In order to raise a pig, Annie needs to have a pig pen that is between 80ft2 to 100ft2.
What is the square footage Annie has available for the pig pen? Is this space big enough for her to raise a pig?
PLEASE HELP I WILL MARK BRAINLIEST IF POSSIBLE!!!!

The ordered pair (-3 , ) is on g(x) ⇒ 1st answer
Step-by-step explanation:
Let us revise the reflection across the axes
- If the function f(x) reflected across the x-axis, then its image is g(x) = - f(x) (change the sign of y)
- If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x) (change the sign of x)
∵
∵ f(x) is reflected across the y-axis to create the function g(x)
- Change the sign of x
∴
To find the point that lies on g(x) substitute x in g(x) by the x-coordinate of the point if the answer equal to the y-coordinate of the point, then the point lies on it if not then the point does not lie on it
∵ The coordinates of the point are (-3 , )
∴ x = -3 and y =
- Substitute x by -3 in g(x)
∵

∴
- Divide up and down by 2
∴
∵ The value of g(x) equal to the y-coordinate of the point
∴ The point (-3 , ) lies on g(x)
The ordered pair (-3 , ) is on g(x)
