Question

Question 1 1 pts State the domain of the function graphed below, f(x) = -(x - 7)2 + 1, using interval notation.

Answer 1

`(-\infty,\infty)`

Explanation:

When looking to find the domain of a function, we have to find it's impediments.

An impediment is either a fraction, in which the denominator cannot be 0, or a even root(square, fourth, ...), in which what is inside the root must not be negative.

In this question, we do not have any of these impediments, so the domain is all real numbers, which in interval notation, can be represented as:

`(-\infty,\infty)`
