# What is the maximum value of # f(x)= 3x^2 - x^3#?

##### 1 Answer

**the max value** will therefore be as

#### Explanation:

the dominant term in this function is the

so for large negative x, the function is effectively **the max value** will therefore be as

equally for large positive x, the function is effectively **the min value** will therefore be as

maybe you are using calculus, in which case you might also be expected to look at:

that will be zero at critical points so **local** min and max.

you can use
