Find the range of the function for the domain {−3, 1, 4.5}. f(x) = 2x^2

D

Step-by-step explanation:

f(x) = 2x^2

f(3) = 2*(-3)^2

f(3) = 2* 9

f(3) = 18

f(1) = 2*(1)^2

f(1) = 2*1

f(1) = 2

f(4.5) = 2*4.5^2

f(4.5) = 2 * 20.25

f(4.5) = 40.5

D

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
