WebAug 4, 2013 · Find the zeros of the ff. Quadratic Functions. 1. F(x) = x2 - 5x – 24 2. F(x) = x2 – 2x -8 3. F(x) = x2 + x – 2 4. F(x) = 3x2 + 9x – 12 5. F(x) = 2x2 + 15x - 8 5. Assignment: Find the zeros of the ff. Quadratic … WebThe zeros of quadratic function are obtained by solving f (x) = 0. For this, we use the quadratic formula: x = [ -b ± √ (b 2 - 4ac) ] / 2a x = [ -3 ± √ {3 2 - 4 (1) (-4)}] / 2 (1) = [ -3 ± √ (9 + 16) ] / 2 = [ -3 ± √25 ] / 2, x = [ -3 + 5 ] / 2, …
WebExample 1: Find the zeros of the quadratic function f (x) = x 2 + 6x + 9. Solution: To find the zeros of the function f (x) = x 2 + 6x + 9, we will first find its factors using the algebraic identity (a + b) 2 = a 2 + 2ab + b 2. We have f (x) = x 2 + 6x + 9 = x 2 + 2 × x × 3 + 3 2 = (x + 3) 2 Now, f (x) = 0 ⇒ (x + 3) 2 = 0 WebStep 1: Graph the quadratic function f(x) = ax2 +bx+c f ( x) = a x 2 + b x + c in the graphing calculator. This is usually done by hitting " y = y = " and then typing the right side of the ...
