Question

Please!!!!!!!!!!!!!!!!!​

Answer 1

know that domain means x-axis values and range means y-axis values. So for your question, we need to determine all the y values of the function which is from 3 to (-7), but to express this algebraically, we need to express it in the manner, 'x<y<z'. For your condition it would be, '-7 < y < 3' (no symbols intended with the '<' and the '3'). Be careful that I arranged '-7' and '3' so that 'y' is less than '3', but is greater '-7'. So for example, 3<y<-7 would be incorrect since you are saying that 'y' is less than '-7' and greater than '-3' which is a whole other parabola. I also chose y to represent the y-axis and range since if we used x, it would refer and confuse to/with the x-axis and domain.

Answer 2

Explanation:

There are two features of a function, domain and range. Domain corresponds to the set of x-values, while range corresponds to the set of y-values. The set of y-values corresponding to this function would be

-7
`<` y
`\leq \\ \\` 2. It can also be written in interval notation as (-7,2] where the parentheses is inclusive of -7 and the square bracket is inclusive of 2.
