Question

Find the domain of the given function. (5 points)

f(x) = sqrt(x+9)/(x+3(x-7)

Answer 1

x ≥ -9, x ≠ -3, x ≠ 7, correct?

Answer 2

Well the domain will be restricted due to the denominator

Answer 3

x ≠ -3, x ≠ 7

Answer 4

and the numerator will be restricted also due to the square root

Answer 5

x ≥ -9, x ≠ -3, x ≠ 7, is correct

Answer 6

Okay

Answer 7

Why can't x be less than -9?

Answer 8

HI!!
because you can't take the square root of a negative number

Answer 9

Of course, my bad. Thank you both.
