Question

The graph of which quadratic equation is shown below?
A.) y = x2 + 4x − 5
B.) y = x2 − 4x − 5
C.) y = −x2 + 4x − 5
D.) y = −x2 − 4x − 5

Answer 1

B - The graph crosses the axes at 1 and 5 so 5 and 1 must be solutions to the equation. B is the only equation that satisfies this and is the 'right way up'.

Answer 2

thank you soo much!!!!
