Questions & Step-by-Step Solutions

In a function f(x) = ax^2 + bx + c, what does the coefficient 'a' determine about the graph?
  • Step 1: Identify the function f(x) = ax^2 + bx + c.
  • Step 2: Look at the coefficient 'a' in front of x^2.
  • Step 3: Determine if 'a' is positive or negative.
  • Step 4: If 'a' is positive, the graph (parabola) opens upwards.
  • Step 5: If 'a' is negative, the graph (parabola) opens downwards.
