The value of F(3) = 27.
Step-by-step explanation:
Step 1:
F(x) is dependent on the value of x.
So x is independent while F(x) is dependent on x i.e. the value of F(x) depends on the value of x.
Step 2:
F(x) =
, if we have the x's value we can calculate the F(x)'s value.
Here the value of x is given as 3 so F(x) when x equals 3 can be calculated.

So F(3) = 27.
3x(x^2 -7x +12) = 3x(x-4)(x-3)
3x=0
x_1 = 0
x-4=0
x_2 = 4
x-3=0
x_3 = 3
hope helped
