P(x) = 2x² + 1<br> What is the inverse for p(x)?
Serhud [2]

Answer:

P^{-1} (x)=\sqrt{\frac{x-1}{2} }

Step-by-step explanation:

1. P(x)=2x^{2} +1

2. y=2x^{2} +1

3.x=2y^{2} +1

4.2y^{2} =x-1

5.y^{2} =\frac{x-1}{2}

6.y=\sqrt{\frac{x-1}{2} }

7.P^{-1} (x)=\sqrt{\frac{x-1}{2} }

What is the slope of a line perpendicular to the line whose equation is 6x+y=66x+y=6. fully reduce your answer?
shepuryov [24]
It looks like your equation repeated twice. I'm assuming it's 6x + y = 6.

I'm going to put your equation into slope-intercept form: y = - 6x + 6.

For the slope to be perpendicular, we do the opposite reciprocal of the slope given. So your slope of a perpendicular line is 1/6.
