$f(x) = a {x}^{2} + bx + c$
the vertex will be
$x = \frac{ - b}{2a} \\ y = \frac{4ac - {b}^{2} }{4a}$

Find the inverse f(x)=6x+7

Lorico [155]

Answer:

$f^{-1}$ (x) = $\frac{x-7}{6}$

Step-by-step explanation:

let y = f(x) , then rearrange making x the subject

y = 6x + 7 ( subtract 7 from both sides )

y - 7 = 6x ( divide both sides by 6 )

$\frac{y-7}{6}$ = x

Change y back into terms of x with x = $f^{-1}$ (x) , then

$f^{-1}$ (x) = $\frac{x-7}{6}$

Let me give you an example
6x + 5x + 14 + 6
So all you is combine 6x and 5x
11x +14 + 6
Then you just combine the other two numbers
11x + 20
