Questions & Step-by-Step Solutions

If f(x) = x^2 - 4x + 4, what is f(2)?
  • Step 1: Identify the function f(x) = x^2 - 4x + 4.
  • Step 2: Substitute x = 2 into the function. This means we replace every x in the function with 2.
  • Step 3: Write the equation with the substitution: f(2) = 2^2 - 4(2) + 4.
  • Step 4: Calculate 2^2, which is 4.
  • Step 5: Calculate -4(2), which is -8.
  • Step 6: Now, rewrite the equation with the calculated values: f(2) = 4 - 8 + 4.
  • Step 7: Simplify the equation: 4 - 8 = -4, then -4 + 4 = 0.
  • Step 8: Therefore, f(2) = 0.
