Question

6. Given the equation: y = x2 + 4x + 3 a. (3 pts) Find the vertex b. (3 pts) Find two other points on the parabola and graph the equation on the grid below 7. (4 pts) Graph the following linear equation on the grid below: y = x-5 3

Answer 1

Dy = n²+ 4n+3 y= n2+40 + 4 / y=/=(n-3)? Vertex = (ny) = (-2,-1) y=1= (2+2)² 2. when when no, y = 3. n = 5, y = (-50²+4(-5)+3 25 20+3 = 8 y=+-4+370. look below cohen n=-1 for graph for graph 3 look belowe. Slope = 32 when no 5. When yog y=5 0=312+5 => n = -5x2 3 - -10% -3.3334 CS Scanned with CamScanner
