If f(x)= -6x+6 then f^-1(x)=

drek231 [11]

Recall that, to get the inverse relation of any expression, we start off by doing a quick switcharoo on the variables, then we solve for "y".

$\bf \stackrel{f(x)}{y}=-6x+6\qquad inverse\implies \boxed{x}=-6\boxed{y}+6
\\\\\\
x-6=-6y\implies \cfrac{x-6}{-6}=y\implies -\cfrac{x}{6}+1=\stackrel{f^{-1}(x)}{y}$

Solve the following quadratic function by using the quadratic formula: x^2 +<br> 2x - 1 = 2 *

elena55 [62]

Answer:

x = 1 or x = -3

Step-by-step explanation:

$ax^{2}$ + bx + c = 0

x = $\frac{-b±\sqrt{b^{2}-4ac } }{2a\\}$

as $x^{2}$ + 2x - 1 = 2 ⇔ $x^{2}$ + 2x - 3 = 0, its solution is

x = $\frac{-2±\sqrt{2^{2}-4 *1*(-3)} }{2*1}$

= $\frac{-2±\sqrt{4+12} }{2}$ = $\frac{-2±\sqrt{16} }{2}$ = $\frac{-2±\ 4 }{2}$

therefore, x = 1 or x = -3

hope this helps! :D

What is the recursive rule for this geometric sequence? 2, 1/2, 1/8, 1/32,

Sav [38]

$a_1=2,\ a_2=\dfrac{1}{2},\ a_3=\dfrac{1}{8};\ a_4=\dfrac{1}{32}\\\\r=\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}=\dfrac{a_4}{a_3}=...\\\\r=\dfrac{\frac{1}{2}}{2}=\dfrac{\frac{1}{8}}{\frac{1}{2}}=\dfrac{\frac{1}{32}}{\frac{1}{8}}=\dfrac{1}{4}\\\\\boxed{a_1=2;\qquad a_n=\dfrac{1}{4}\cdot a_{n-1}}$
