What is the inverse of the function f(x) = 2x – 10?
Dvinal [7]
ANSWER:

f(x)⁻¹ = (x+10)/2

WORKING OUT:

f(x) = 2x - 10

y = 2x - 10

*Replace all 'y' values with 'x' and vice versa*

x = 2y - 10

*Make y the subject of the equation*

2y = x+10

y = (x+10)/2

Stuck, help please !
Olin [163]

Use the fundamental trigonometric equation

\sin^2(x) + \cos^2(x) = 1 \implies \sin^2(x) = 1-\cos^2(x)

To rewrite the equation as

1-\cos^2(x) = 1-\cos(x)

Subtract 1 from both sides:

-\cos^2(x) = -\cos(x)

Add \cos^2(x) to both sides:

\cos^2(x) - \cos(x) = 0 \iff \cos(x)\left(\cos(x)-1\right)=0

A multipication is zero if and only if one of the factors is zero. So, the solutions are given by

\cos(x)=0 \iff x=\dfrac{\pi}{2}+k\pi,\quad k \in \mathbb{Z}

or

\cos(x)-1=0 \iff \cos(x)=1 \iff x=2k\pi,\quad k \in \mathbb{Z}
