For what value(s) of x are the following undefined?
5x^2+x+1 / x^2+4

In Real numbers: none (defined for all real numbers)

In Complex numbers: not defined for x = 2i, -2i

Step-by-step explanation:

Fraction becomes undefined when the denominator = 0

x² + 4 = 0

Has no real solutions

The fraction is defined for all real values of x

x² + 4 = 0

x² = -4

x = 2i, -2i

The fraction is not defined for x = +/-2i (in Complex Numbers)

NONE

Step-by-step explanation:

The function 5x^2+x+1/ x^2+4 is defined for all real numbers because the denominator x² + 4 ≠ 0 for all real numbers

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
