Graph the integrand and use areas to evaluate the integral. Integral from negative 3 to 3 left parenthesis 4 plus StartRoot 9 minus x squared EndRoot right parenthesis dx Question content area bottom Part 1 Choose the correct graph of the integrand below. A. -3 3 0 8 x y A coordinate system has a horizontal x-axis from negative 3 to 3 in increments of 1 and a vertical y-axis from 0 to 8 in increments of 1. A curve starts at (negative 3, 7), falls to a minimum at (0, 4), and rises to the point (3, 7). B. -3 3 0 8 x y A coordinate system has a horizontal x-axis from negative 3 to 3 in increments of 1 and a vertical y-axis from 0 to 8 in increments of 1. A curve starts at (negative 3, 4), rises to a maximum at (0, 7), and falls to the point (3, 4). C. -3 3 0 8 x y A coordinate system has a horizontal x-axis from negative 3 to 3 in increments of 1 and a vertical y-axis from 0 to 8 in increments of 1. A curve starts at (negative 3, 0), rises to a maximum at (0, 3), and falls to the point (3, 0). D. -3 3 0 8 x y A coordinate system has a horizontal x-axis from negative 3 to 3 in increments of 1 and a vertical y-axis from 0 to 8 in increments of 1. A curve starts at (negative 3, 3), falls to a minimum at (0, 0), and rises to the point (3, 3).
