Aquadratic function has a line of symmetry at x=-3.5 and zero at -9 what is the distance from the given zero to line of symmetry

If a quadratic function has zero at x=-9, then point (-9,0) lies on the graph of quadratic function.

A line of symmetry has equation x=-3.5 that is x+3.5=0.

Use formula for the distance from point to the line AX+By+C=0:

Thus,

the distance is 5.5 units.

range is infinite on both x and y axis positive and negative

i think the length is 12 and the width is 17
