Question 1088881

The axis of symmetry for f(x)=x^2 + 3x-2 is x=?
A. 3
B. -1
C. 1
D. -1.5
<pre>{{{matrix(1,6, Axis, of, "symmetry:", x, "=", - b/(2a))}}}, where: a = 1, and b = 3
We then get: {{{highlight_green(matrix(1,12, Axis, of, "symmetry:", x, "=", - 3/(2 * 1), "=", - 3/2, or, - 1.5, "(CHOICE", "D.)"))}}}
That's all!!
