-3788 answer
We can plug the given point in each equation and check if it satisfies it
1.
5x - 2y + 1 > 0
5(-2)-2(-1)+1>0
-10+2+1>0
-7>0 (false)
2.
-5x + 2y + 1 > 0
-5(-2) + 2(-1) + 1 > 0
10-2+1>0
9>0
so -5x + 2y + 1 > 0 satisfies the given point (-2,-1)
F(x) = x² + 4
y = x² + 4
First, I reverse the equation to be
x² + 4 = y
Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)
Last, change into invers function
f⁻¹(x) = √(x - 4)
I think it’s the third one and the last two. I’m sorry if it’s wrong
