The correct answers are A for Q5,
D for Q6, and C for Q7
A
D
C
The Pythagorean Therom is most helpful
A^2 + B^2 = C^2
Answer:
Graph or make a table of the function.
Step-by-step explanation:
When you graph the function just look on the graph to see that point is part of your function. Same would go for the table. Just look and see if your numbers match.
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
I dont really feel like graphing it out but i can explain it. so lets say that you had some graph points and when you drew them together it was the shape of a circle so make a line down that circle and the rule is if that circle passes through that line you drew more than 2 times it is not a function, and if it only passes through that line once then it is a function.
I don't see the problem on my screen try reposting it?
