In a quadratic equation, if the coefficient of x^2 is negative, what can be inferred about the graph?
Steps
Concepts
Step 1: Understand what a quadratic equation is. It is usually in the form of ax^2 + bx + c, where a, b, and c are numbers.
Step 2: Identify the coefficient of x^2, which is 'a'.
Step 3: Check if 'a' is negative. A negative number is less than zero.
Step 4: Know that if 'a' is negative, the shape of the graph is a parabola.
