Which function has an inverse function?
f(x)=(x+3)/5
f(x)=x^5-3
f(x)=x^4/7+27
f(x)=1/x^2
need ! you

Example 5: If f(x) = 2x – 5, find the inverse. This function passes the Horizontal Line Test which means it is a onetoone function that has an inverse. y = 2x – 5 Change f(x) to y. x = 2y – 5 Switch x and y. Solve for y by adding 5 to each side and then dividing each side by 2.

w'x is 0.

hope it

it would open into a square depending on the type of envelope i’m not sure about the second part
