Use the graph of the function f(x) to locate the local extrema and identify the intervals where the function is concave up and concave down.
A. Local minimum at x = 3 ; local maximum at x = -3 ; concave up on (-?, -3) and (3, ?); concave down on (-3, 3) B. Local minimum at x = 3 ; local maximum at x = -3 ; concave up on (0, ?); concave down on (-?, 0) C. Local minimum at x = 3 ; local maximum at x = -3 ; concave down on (0, ?); concave up on (-?, 0) D. Local minimum at x = 3 ; local maximum at x = -3 ; concave down on (-?, -3) and (3, ?); concave up on (-3, 3)
Factor the given factor from the expression.x3/8; x7/8 + 3x3/8
A. x1/8(x4/8 + 3) B. x1/8(x7/8 + 3) C. x3/8(x1/2 + 3) D. x3/8(x-1/2 + 3)
Provide an appropriate response.Divide and simplify: (4x3 + 5x - 3) ÷ (2x + 1)
