Question

Determine whether the graph of y = x2 + 4x − 7 has a maximum or minimum point, then find the maximum or minimum value.

Minimum; (-11, -2)

Maximum; (-11, -2)

Maximum; (-2, -11)

Minimum; (-2, -11)

Answer 1

minimum value

Answer 2

\[-\frac{b}{2a}=-\frac{4}{2\times 1}=-2\]
\[(-2)^2+4\times (-2)-7=4-8-7=-11\]

Answer 3

i dont knowwwwwww
