Question 4(12 points)Refer to Sections 2,3,4 in the course notes. You will need to compute y' and y' and evaluate each at x=-1Consider the function: f(x)=5x4-7x23x-2. Determine whether each statement about the function is true or false at the point where x=-1. The function is concave down at x=-1There is a relative maximum at x=-1The function is concave up at x=-1TrueThe function is decreasingFalse at x=-1 The function is increasing at x=-1
