Question

Graph this equations stating the x and y intercepts,the co-ordinates of the vertex,the line of symmetry and whether the graph has maximum or minimum point.

1. y = 2x^2
2. y = (x + 3)^2

Answer 1

1) PARABOLA WITH +VE Y-AXIS AS THE LINE OF SYMMETRY AND PASSES THROUGH (0,0)
2) PARABOLA WITH X=-3 AS THE LINE OF SYMMETRY(UPWARD) x-intercept (-3,0) and y-intercept (0,9)
in order to know x-intercpt put y=0 and for y-intercept put x=0
