Graphing a quadratic function
WebThe graph of the quadratic function f(x)=ax2+bx+c, a ≠ 0 is called a parabola. Important features of parabolas are: • The graph of a parabola is cup shaped. • The graph opens upward if a > 0 and downward if a < 0. • The vertex is the turning point of the parabola. • If the parabola opens upward, the vertex is the lowest point on the ...

WebTips when using the quadratic formula Be careful that the equation is arranged in the right form: ax^2 + bx + c = 0 ax2 + bx + c = 0 or it won’t work! Make sure you take the square root of the whole (b^2 - 4ac) (b2 − 4ac) , and that 2a 2a is the denominator of everything above it Watch your negatives: b^2 b2 can’t be negative, so if b b WebA parabola is defined as 𝑦 = 𝑎𝑥² + 𝑏𝑥 + 𝑐 for 𝑎 ≠ 0 By factoring out 𝑎 and completing the square, we get 𝑦 = 𝑎 (𝑥² + (𝑏 ∕ 𝑎)𝑥) + 𝑐 = = 𝑎 (𝑥 + 𝑏 ∕ (2𝑎))² + 𝑐 − 𝑏² ∕ (4𝑎) With ℎ = −𝑏 ∕ (2𝑎) and 𝑘 = 𝑐 − 𝑏² ∕ (4𝑎) we get 𝑦 = 𝑎 (𝑥 − ℎ)² + 𝑘 (𝑥 − ℎ)² ≥ 0 for all 𝑥 So the parabola will have a vertex when (𝑥 − ℎ)² = 0 ⇔ 𝑥 = ℎ ⇒ 𝑦 = 𝑘
