Find the range for the function k(n) = 2n^2 when d = {–2, 1, 3}.

a lota if you answer!

R = { 8, 2, 18}

Step-by-step explanation:

The range of the function is the set of function values or y-values. To find them, substitute the values x = -2, 1, and 3 into the function.

k(n) = 2n^2

k(-2) = 2(-2)^2

k(-2) = 2(4) = 8

k(n) = 2n^2

k(1) = 2(1)^2

k(1) = 2(1) = 2

k(n) = 2n^2

k(3) = 2(3)^2

k(3) = 2(9) = 18

The range is R = { 8, 2, 18}.

hi, i am not sure about this one but i think its d,

hope this !

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
