Final answer:

The indicated function values for f(x) = 2x^2 - 3x - 7 are found by substituting the given x-values into the function. These values are calculated to be f(0) = -7, f(1) = -8, f(-1) = -2, and f(2) = -5.

Step-by-step explanation:

The student has asked to find the indicated function values for f(x) = 2x2 - 3x - 7. This is a question of evaluating a quadratic function at given x-values. Let's calculate them step by step:

  • f(0): When x = 0, the function simplifies to f(0) = 2(0)2 - 3(0) - 7 = -7.
  • f(1): When x = 1, the function simplifies to f(1) = 2(1)2 - 3(1) - 7 = 2 - 3 - 7 = -8.
  • f(-1): When x = -1, the function simplifies to f(-1) = 2(-1)2 - 3(-1) - 7 = 2 + 3 - 7 = -2.
  • f(2): When x = 2, the function simplifies to f(2) = 2(2)2 - 3(2) - 7 = 8 - 6 - 7 = -5.

So, the function values are:

  • f(0) = -7
  • f(1) = -8
  • f(-1) = -2
  • f(2) = -5
