What is the range of y = x2 – 1, given a domain of {-2,-1,0, 1, 2}? A. R:{-5, -2, -1,0.3)
B. R: -1 O
C. R:y > -1
OD. R:{-1,0,3}

D

Step-by-step explanation:

Basically, what the question is asking you to do is plug in each of the domain numbers (because domain represents X) and solve for y. Btw, after plugging in each domain to separate equations, if you end up with two numbers being the exact same, you only need to put one of them, hence why there are only 3 numbers in this answer. Hope with helps, any questions just ask me.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
