Hello there!
Our equation is this:
y = [tex] \frac{5}{ x^{2} + 1} [/tex] - 1
If x = 1, we can plug it in and then try to solve for y.
Let's plug in 1 for x.
y = [tex] \frac{5}{ 1^{2} + 1} [/tex] - 1
y = [tex] \frac{5}{1 + 1} [/tex] - 1
y = [tex] \frac{5}{2} [/tex] - 1
y = 2.5 - 1
y = 1.5
I hope this helps!
