Y = x^2 - 2x - 3 x = -1

It’s not -2 apparently ‍♀️

This is how the equation was written:

= (-1)^2 -2•-1-3

I must be missing something cause they said it’s 0 but I have no idea why.
Can someone explain?

good for u

step-by-step explanation:

the cat is blue because the probability of extension towards the prefix of the diameter of the circle could only mathematically equal to the sum of the roots of the carrots from   your garden.

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
