PCAT Quantitative Reasoning – Function Graph Integration

Find the area under curve y=f(x) shown below.

  1. -2+C
  2. -2x+6+C
  3. x2+6x+C
  4. -2x2+6x+C

C is correct. To find the area under the curve, we must first identify the function f (x) that this curve represents, and then we must find the integral to determine the area under the curve.
