WebMay 28, 2024 · 1 Answer Jim G. May 28, 2024 see explanation Explanation: the graph of y = (x + 3)2 is the graph of y = x2 translated 3 units to the left the graph of y = x2 is graph {x^2 [-10, 10, -5, 5]} the graph of y = (x + 3)2 the point (0,0) → ( − 3,0) choosing some values of x x = 0 → y = 32 = 9 → (0,9) ← y-intercept x = − 5 → y = 22 = 4 → ( −5,4) WebDec 29, 2024 · The x-vertex of a quadratic equation y = ax2 + bx +c is given by − b 2a. Plugging in a = 1, b = 6, and c = 5, we find that the x-vertex is − 6 2 = − 3. Now we plug in x = − 3 into y = x2 + 6x +5 to get the y-vertex, which is −4. So our vertex is ( −3, −4).
