For x 1, x 2 ∈ R, consider We note that there are point, x1 and x 2 with x 1 ≠ x 2 and f (x 1) = f (x 2), for instance, if we take x 1 = 2 and x 2 = 1/2, then we have f (x 1) =2/5 and f(x 2) =2/5 but 2 ≠ 1/2 Hence f is not oneone Also, f is not onto for if so then for 1∈R ∃ x ∈ R such that f (x) = 1 which gives x/(x 2 1) =1 But there is no such x in the domain R, since theWEBSITE http//wwwteachertubecom F(x) = 2x1The equation is in standard form xf=x^ {2}6x8 x f = x 2 − 6 x 8 Divide both sides by x Divide both sides by x \frac {xf} {x}=\frac {\left (x4\right)\left (x2\right)} {x} x x f = x ( x − 4) ( x − 2) Dividing by x undoes the multiplication by x Dividing by x undoes the multiplication by x

So, the inverse of f(x) = 2x3 is written f1 (y) = (y3)/2 (I also used y instead of x to show that we are using a different value) Back to Where We Started The cool thing about the inverse is that it should give us back the original value When the function f turns the apple into a banana, Then the inverse function f1 turns the banana back to the apple Example Using the formulas fromF/X2 Directed by Richard Franklin With Bryan Brown, Brian Dennehy, Rachel Ticotin, Joanna Gleason A special effects man helps his girlfriend's ex, a cop, with a sting operation, where the ex gets killed Something's off and he investigates with help from an excop PI friendFree functions calculator explore function domain, range, intercepts, extreme points and asymptotes stepbystep
