Answer:

A::True

Step-by-step explanation:

For the quadratic function the domain is all real numbers since the horizontal extent of the graph is the whole real number line. Because the graph does not include any negative values for the range, the range is only non-negative real numbers.

Which equation is quadratic in form?

Drupady [299]

we know that

A quadratic equation is a polynomial with an order of two. Its general form is

$ax^{2} + bx + c = 0$

case a) $6(x + 2)^{2} + 8x + 2 + 1 = 0$

$6(x + 2)^{2} + 8x + 2 + 1 = 0 \\ 6(x^{2} +4x+4)+8x+3=0\\ 6x^{2} +24x+24+8x+3=0\\ 6x^{2} +32x+27=0\\\\ a=6\\ b=32\\ c=27$

The case a) is a quadratic equation

case b) $6x^{4} + 7x^{2} - 3 = 0$

The case b) is a grade $4$ polynomial

case c) $5x^{6} + x^{4} + 12 = 0$

The case c) is a grade $6$ polynomial

case d) $x^{9} + x^{3} - 10 = 0$

The case d) is a grade $9$ polynomial

therefore

the answer is

$6(x + 2)^{2} + 8x + 2 + 1 = 0$

mamaluj [8]

Answer:

Step-by-step explanation:

In a box and whisker plot, the line inside of the box is the median. Using the numbers at the bottom of the graph, you can tell that the median income for police officers is 30 thousand dollars. The median income for musicians is also 30 thousand dollars. So the second answer is correct.
