So to start off you subtract y2 - y1/x2 - x1. This should look like -5 - -1/ -4 - -4. Now you do the math and you should get -4/0. Therefore the slope is undefined.
F⁻¹(x) stands for the invers of function f(x). The inverse of f(x) is equal to x. We need to solve for x.
solve for x
f(x) = 2x + 2
2x + 2 = f(x)
2x = f(x) - 2
x =

f⁻¹(x) =

Determine the value of f⁻¹(x) when x = 4
f⁻¹(x) =

f⁻¹(4) =

f⁻¹(4) =

f⁻¹(4) = 1
When x = 4, the value of f⁻¹(x) is equal to 1
Answer:
B. I belive ^_^
Step-by-step explanation:
The maximum area is the area that uses half the fence (150 ft) for the side parallel to the barn and the other half for the ends of the pen (75 ft each). That area is 11,250 ft^2.
The length would be 7 inches and the width would be 6 inches <span>☆ I hope this helps! If you need help showing work or anything I'd be happy to let you know in the comments :0</span>
