Find a value(s) that makes the expression
y^2 - 16
---------- undefined.
y^2 + 16
y=4i?
yes, and also -4i
y^2+16 = (y+4i)(y-4i)
Thank you!
To find the value(s) that make the expression undefined, we need to look at the denominator of the expression, which is y^2 + 16. If the denominator equals zero, then the expression is undefined.
If we substitute y = 4i into the denominator, we have:
(4i)^2 + 16
Simplifying, we get:
(-16 + 16) + 16 = 16
Since the denominator is not equal to zero, the given expression is not undefined when y = 4i.
