The sketch is the curve of y = ax2 + bx + c. Find a, b and c respectively

The sketch is the curve of y = ax2 + bx + c. Find a, b and c respectively

Answer Details

Given the graph and the curve y = ax2 + bx + c the roots are x - 2 and 2 while its equation (x + 2)(x - 2) = y

y = x2 - 4 i.e. y = x2 + 0x - 4

a = 1, b = 0 and c = -4
