Question

type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.

the domain of the function f(x)= 3x^3 is {2,5} what is the function's range?
the range of the function f(x)=3x^3 when its domain is {2,5} is_______?

Answer 1

@hayhayz

Answer 2

the domain {2,5} means that the only x-values included are x = 2 and x = 5

evaluate f(x) = 3x^3 when x = 2 and when x = 5 to get your range

Answer 3

= 3(2)^3

then repeat for x = 5

Answer 4

Its an increasing function... So
f(x) increase from 2 to 5
So its range is from f(2) to f(5).

Answer 5

yes
and f(2) means the value of the function when x = 2

in this case its 3(2)^3

Answer 6

thank yall.
