Question

I need #5 and #7 answered please.

Answer 1

Explanation:

5). y = 4 - x²

Table for the points on this function will be,

x -2 -1 0 1 2

y 0 3 4 3 0

Therefore, Domain of the function will be: (-∞, ∞)

And Range of the function will be : (-∞, 2]

7).
`y=2+√(x-1)`

This function is defined from the values of x ≥ 1

Table for the input-output values of this function is,

x 1 2 5 10 17

y 2 3 4 5 6

Therefore, Domain of the function will be: [1, ∞)

And Range of the function : [2, ∞)
