Answer:

  • Option A is correct

Step-by-step explanation:

<u>Given functions f(x) and g(x). f(x) is:</u>

  • f(x) = x^2 + 4x + 6

<u>Converted into vertex form, it is:</u>

  • f(x) = (x + 2)^2 + 2

<u>g(x) has vertex at (-2, -14), it's vertex form is:</u>

  • g(x) = (x + 2)^2 - 14

Comparing f(x) and g(x) we see both have same x- coordinate of the vertex (x = -2).

Both have positive leading factors, therefore the vertex is their minimum point.

Function f(x) has vertex above the x-axis as y-coordinate of the vertex is positive. Hence no intersection with x-axis.

Function g(x) has negative y-coordinate of the vertex, so it has two intersections with x-axis.

Correct choice is A

What is the slope of the line that passes (-11,2) and (-1, -13). Plz show your work.
ANEK [815]

Answer:

Slope = -3/2 or -1.5

Step-by-step explanation:

The Formula for slope is (The picture linked)

So, \frac{-13-2}{-1-(-11)}

Which is equal to... \frac{-15}{10} when simplified

Which is equal to \frac{-3}{2} or -1.5 which is the slope

sesenic [268]

Answer

Area of a circle is defined as

Area of a circle is defined asA = πr²

Area of a circle is defined asA = πr²Where

Area of a circle is defined asA = πr²WhereA is the area of the circle

Area of a circle is defined asA = πr²WhereA is the area of the circler Is the radius of the circle

Area of a circle is defined asA = πr²WhereA is the area of the circler Is the radius of the circleπ is a constant = 3.142

Area of a circle is defined asA = πr²WhereA is the area of the circler Is the radius of the circleπ is a constant = 3.142Then,
