Topic 3The definition is satisfied. The functions f and g are inverses.Problem 2. Let f(x) = x2 and g(x) = x½. Show that they are inverses of one another. (The domain of f must be restricted to x 0.)To show that they are inverses, we must show that they satisfy the ...
So, the inverse of f(x) = 2x+3 is written:f-1(y) = (y-3)/2(I also used y instead of x to show that we are using a different value.)Back to Where We StartedThe cool thing about the inverse is that it should give us back the original value:...
Find the inverse of y = 3x − 2.Here's how the inverse-finding process works: I start with my original function: y = 3x − 2 Now I'll try to solve for "x =": y+2=3xy+23=xy+23y+2=3x=x Once I have "x=", I'll switch x and y; the new "y=" is the inverse....
A function ff is one-to-one if and only if every horizontal line intersects the graph of ff no more than once. Figure 2. (a) The function f(x)=x2f(x)=x2 is not one-to-one because it fails the horizontal line test. (b) The function f(x)=x3f(x)=x3 is one-to-one because...
Given f(x) = 3(x -2)^3. Find the inverse function of f(x). What is the inverse of the function f(x) = 2x + 1? What is the inverse of the function f(x) = x/5 - 2? What is the inverse function of f(x) = 3x - 3?
