Step 1) Replace f(x) with y: y= 2x - 7
Step 2) Switch around the x and y values: x = 2y - 7
Step 3) Solve to find y by itself: x = 2y - 7 x ...

(2x+3)(x-1)

At a stationary point of y, dy/dx = 0.Step 1: Let's find dy/dx first by differentiating. To differentiate the product of two functions, we can use the product rule...

Ln(3x-7)=5 Remove logs from both sides 3x-7=e⁵Rearrange to make x the subject3x=e⁵+7x=e⁵+7 3

x = 3, y = 2
