I am having trouble answering this question. Please help. I have until 11 pm to answer this.

Given the function g(x) -4x + 18x7 - 120x, find the first derivative, 9 (I). g'(I) Notice that g'(I) = 0 when I - 2, that is, g (2) = 0. Now, we want to know whether there is a local minimum or local maximum at a = 2, so we will use the second derivative test. Find the second derivative, g' '(x). Evaluate g (2). 9 (2) = Based on the sign of this number, does this mean the graph of g(T) is concave up or concave down at c = 2? [Answer either up or down -- watch your spelling!!] At x = 2 the graph of g(I) is concave Based on the concavity of g() at x = 2, does this mean that there is a local minimum or local maximum at c = 2? [Answer either minimum or maximum -- watch your spelling! !] At = 2 there is a local Question Help: DVideo Submit
