Step-by-step explanation:

Step 1: Define

Identify

f(x) = x² + c

f(4) = -7

Step 2: Solve for c

  1. Substitute in variables [Function f(x)]:                                                             -7 = 4² + c
  2. Evaluate exponents:                                                                                        -7 = 16 + c
  3. [Subtraction Property of Equality] Subtract 16 on both sides:                       -23 = c
