Question

specify the domain for the function f(x)=1/x^2-5x+25
a.)(-5/2,5/2)
b.)(-infinity,infinity)
c.)(-infinity,5-square root of 10/2)U(5+square root of 10/2, infinity)
d.)(-infinity, 5-5 square root of 3/2)U(5+5 square root of 3/2, infinity

Answer 1

yikes

Answer 2

set
\[x^2-5x+25=0\] and solve for x

Answer 3

since there is no real solution to that equation, go with \((-\infty, \infty)\)

Answer 4

thank u!
