Help?

Answer 1

Find the range of each function with domain {-2,0,3.5}

22. f(x)= -2x^2
23. g(x)= 10-x^3
24. y=5x-1

Answer 2

the easy way to visualize this is to remember that the domain is the x values. so just plug the domain into each function to complete a t table and then graph them individually. you can find the range without graphing 2 of them with the information given

Answer 3

i just dont understand

Answer 4

alright the domain is the set of x values that satisfy a function. here is a t table

starting with problem 22. you want to plug these x values in one at a time to get their corresponding y values. remember that f(x)=y so you can rewrite the functions y=-2x^2

Answer 5

y=-2x^2
