Question

Please help; I don't know how to do this at all!!
`√((t+9)(t-5))`
`√((t+9)(t-5))`Find the domain for the function f(t) = √(t+9)(t-5)

Answer 1

t》5 or t《-9

Explanation:

f(t) = √(t+9)(t-5)

For a function to be defined, under the radical should be non-negative values

(t+9)(t-5)》0

Roots: 5, -9

t《-9 or t》5
