Question

someone please help me solve....
f(x)=5x+2-3

Answer 1

There is nothing to solve. Please post the ENTIRE question and some of your OWN work.

Answer 2

2.Create your own function to teach the Martians about functions. Your function must contain at least two different operations.
3.Using complete sentences, prove to Splott and Fizzle that your function is a legitimate function.
4.Using your function, explain to the Martians how to solve for f(3). Show your work and explain each step using complete sentences.
5.Using complete sentences, describe to the Martians how to find the inverse of your function.
6.The Martians ask you to explain one last thing, Ultimate Math Ambassador. They ask you to create a new function, h(x). Then assign any number to x. Using complete sentences, explain whether f(h(x)) and h(f(x)) will always result in the same number. You will use the function f(x) that you created in problem number 2.

I figured I could use that function that I put for the problem.. but idk what to do next

Answer 3

1) f(x) = 5x + 2 is fine. Not sure what that -3 is doing in there.
2) Find the inverse. h(x) = (x-2)/5. You should know how to do that. Hint: "Swap and Solve"?

Now, answer the questions of the silly Martians. I hope they don't destroy the Earth.
