# Find features of quadratic functions

Find the y-intercept, the zeroes ("roots"), and the vertex of the graphs of quadratic functions. Functions are given in standard, vertex, and factored form.

### Problem

The following function is quadratic, and therefore its graph is a parabola.
space, h, left parenthesis, r, right parenthesis, equals, r, start superscript, 2, end superscript, plus, 11, r, minus, 26
Fill in the zeros of the function in ascending order.
space, r, start subscript, 1, end subscript, equals
space, r, start subscript, 2, end subscript, equals
Fill in the coordinates of the vertex of the parabola.
space, left parenthesis
comma
right parenthesis
Complete the equation of the parabola's line of symmetry.
space, r, equals
