To identify vertex, axis of symmetry, x- intercepts.
Answer to Problem 7RE
Standard form is
x- intercepts not exist.
Explanation of Solution
Given information:
Consider
Calculation:
Convert in to standard form by completing the square
Graph:
The graph of
From the above graph,
The vertex is the point at which the parabola changes its direction.
vertex is
The axis of symmetry divides the graph in to two equal parts.
axis of symmetry is
x- intercept means the point at which the graph crosses x- axis.
x- intercepts not exist.
