Take a look at this.

The domain and range are clear here!


This is for the first question.

Answer 12

this was a little tricky
the range is the set of output values that satisfy the function from lowest to highest
when x is negative the square is positive and you can subtract 2
when x is -1 then y = -2
when x = 0 y = -1
when x is positive then y is positive
so the lowest is -2

Answer 13

@triciaal so for #2 it would be B" correct because y is greater than or equal to -2?

Answer 14

@3mar you input -1 in the equation instead of -2
@iwanttogotostanford see the graph but minimum at -2

Answer 15

correct
