Question

Draw f(x)=-x^2+5. Plot the point for the vertex, and label the coordinate as a maximum or minimum, draw and write the equation for the axis of symmetry

Answer 1

graphing

then,

vertex: (0,5)

the coordinate is a maximum

equation of axis of symmetry:

$\begin{gathered} x=-\frac{b}{2a} \\ \text{where b = 0 and a = -1},\text{ so} \\ x=-\frac{0}{2(-1)}=0 \end{gathered}$

therefore,

axis of symmetry is at: x = 0
