Which of the following is a complex number?

1 answer:

4 0

You'll be disappointed to find out these are *all* complex numbers, because the set of real numbers is a subset of the complexes.

Probably the question means to ask, "which of these numbers is strictly non-real?" in which case D would be the answer because it contains the square root of a negative number that introduces the imaginary unit <em>i</em>. All the other options are strictly real numbers.

Find the axis of symmetry and vertex of the following y= -2x2-3x+2

Mnenie [13.5K]

Y= -2x²-3x+2, (form y = ax² +b .x + c

The parabola opens downward & hence it's Vertex is a MAXIMUM.

We know that the axis of symmetry is -b/2a ==>3/(-4) ==>
x= - 3/4 (axis of symmetry. At x=-3/4 , y = 25/8 = 3.125

Hence the axis of symmetry is x= - 3/4 & the vertex is at (-3/4, 25/8)
