Question

4. What is the relative maximum and minimum of the function?

function symbolf(x)= 2x3 + x2 – 11x
(1 point)The relative maximum is at (–1.53, 8.3) and the relative minimum is at (1.2, –12.01).
The relative maximum is at (–1.53, 12.01) and the relative minimum is at (1.2, –8.3).
The relative maximum is at (–1.2, 8.3) and the relative minimum is at (1.53, –12.01).
The relative maximum is at (–1.2, 12.01) and the relative minimum is at (1.53, –8.3).

Answer 1

do you know the double derivative test?

Answer 2

no

Answer 3

first find the first derivative of the function and obtain the critical points by setting the first derivative to zero.then follow these steps http://www.mathwords.com/s/second_derivative_test.htm
