If f(x) = x2 – 1 and g(x) = 2x – 3, what is the domain of (fºg)(x)?

(-∞, ∞)

Step-by-step explanation:

Given,

Then (fºg)(x) would be ,

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

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

b) well because you get well

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
