Given f(x) = the quantity of 2x minus 2 divided by 4, solve for f−1(3).

spin [16.1K]

Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7

Find the axis of symmetry of 2x^2 + 12x + 16 Show your work

raketka [301]

The vertex form:

$y=a(x-h)^2+k\\\\(h,\ k)-vertex$

The axis of symetry is x = h.

$y=ax^2+bx+c\to h=\dfrac{-b}{2a}$

We have

$y=2x^2+12x+16\to a=2,\ b=12,\ c=16$

Substitute:

$h=\dfrac{-12}{(2)(2)}=\dfrac{-12}{4}=-3$

<h3>Answer: x = -3</h3>

If f(x) = (3x + 8)/(2x - A) and f(0) = -2, what is the value of A?

Mrac [35]

Using the given info, we can determine that
$(3(0) + 8) \div (2(0) - a) = - 2$
simplify
$8 \div - a = - 2$
multiply both sides by -a
and divide each side by -2
$4 = a$
A = 4
