Answer 1

so the first one plug 5 in for x for both functions and then multiply the answers together.
the second one multiply the two functions together and then simplify it
the third one everytime you see an x make it a y and then make the f(x) into x and then solve for y so you basically undo everything from the one side to the other
the fourth one means the equation =8 so what value of x would make the equation =8
