Question 1011897: Good Morning friends,
I need to understand and figure out the function values. Simplify and show my work. this seems to be one long question and I am so confused. Thanking you in advance, Betty
Simplify or is the root a real number
f(x)= 3 square root x-6
find f(-21)
find f(33)
find f(131)
find f(-2)

Hi there,
I'm not sure if you mean f(x)= cube root x - 6
I intend to assume this is the case.
f(x)= cube root x - 6
f(-21) = cube root (-21 - 6)
f(-21) = cube root (-27)
f(-21) = -3
f(33) cube root (33 - 6)
f(33) cube root (27)
f(33) = 3
f(131) = cube root (131 - 6)
f(131) = cube root (125)
f(131) = 5
f(-2) = cube root (-2 -6)
f(-2) = cube root (-8)
f(-2) = -2
Hope this helps :-)
