Answer:

(-∞, ∞)

Step-by-step explanation:

Given,

f(x)=x^2-1 \ and\ g(x)=2x-3

Then (fºg)(x) would be ,

(2x-3)^2-1\\4x^2-12x+9-1\\4x^2-12x+8

Since this is a polynomial, we know domain of a polynomial is all real number.

Therefore the domain of this (fºg)(x) is (-∞, ∞).

Answer:

0.24 its opposite value is - 0.24

1/4 its opposite value is -1/4

0

-5 its opposite value is 5

240 which is positive and its opposite value is -240

Step-by-step explanation:

hey

from the given statement we can see that question demand is about the opposite values. so

as our first value is 0.24 its opposite value is - 0.24

then move on next value is 1/4

its opposite value is -1/4

0 is a neutral value it neither positive or negative

move on to the next value which is -5 who is already negative

so we take a positive value that is 5

again move to 240 which is positive and its opposite value is -240

Hope it will be brainliest to you
