How to evaluate this f (x) = -x^+1 for x =-3
sukhopar [10]
Just plug in -3 for x. So it will be -(-3)^+ 1
Which is 3^+1.
I'm confused by your ^ sign I'm not sure if this is supposed to be squared or not...? But just solve/simplify the equation.
Hope this helps!

How to distribute this problem:<br> (x-8)^2 + 16
Usimov [2.4K]

Answer:

We conclude that:

\left(x-8\right)^2+16=x^2-16x+80

Step-by-step explanation:

Given the equation

\left(x-8\right)^2\:+\:16

First, solve (x - 8)²

Apply Perfect Square formula:    (a - b)² = a² - 2ab + b²

a=x,\:\:b=8

\left(x-8\right)^2=x^2-2x\cdot \:\:8+8^2

             =x^2-16x+64

so the expression becomes

\left(x-8\right)^2+16=x^2-16x+64+16

                     =x^2-16x+80           Add the numbers: 64+16=80

Therefore, we conclude that:

\left(x-8\right)^2+16=x^2-16x+80
