Answer:
(1.5,0)
(.5,0)
Step-by-step explanation:
Quadratic formula below
We first need to move everything to one side of the equation
4x²-8x+3=0
Then plug everything in
(8±√(-8²-4*4*3))/(2*4)
(8±√16)/8
To calculate the ± we need to do when where it's adding and then negative
we have
(8+4)/8=3/2
and hten
(8-4)/8=1/2
Answer:
f-1(x)=-x-
Step-by-step explanation:
First, switch f(x) to the variable "y".
y=-x-8
Next, swap "x" and "y" with each other.
x=-y-8
Next, lets move the denominator of 2 to the other side by multiplying both sides by 2. Your result will be...
2x=-3y-16
Now move -16 to the left side.
16+2x=-3y
To get "y" by itself, lets divide each side by -3. Our result is...
y=-x-
To finish the problem off, replace y with f-1(x) and your complete answer will be...
f-1(x)=-x-
Can we see the statement plz
