Answer:

Discontinuities are created when the denominator of the rational expression equals zero (because division by zero is undefined). Graphically, this is usually represented by a dashed vertical line indicating a vertical asymptote.

Which property is used 2(x+4)=2x+8

Elenna [48]

Answer:

Apply the distributive property

2x+2(4)=2x+8

Multiply 2 by 4

2x+8=2x+8

Move all terms containing x to the left and subtract 2x

2x+8-2x=8

Combine the opposite terms

2x+8-2x

Subtract 2x from 2x

0+8=8

8=8

All real number

The directrix and vertex of a parabola are shown on the graph. What is the vertex form of the equation for the associated parabo

tresset_1 [31]

Considering the directrix and vertex given in the graph, the equation of the parabola is:

B. $x = -\frac{1}{4}(y + 2)^2 - 2$

<h3>What is the equation of a parabola given it’s vertex?</h3>

The equation of a quadratic function, of vertex (h,k), is given by:

(y - k)² = 4p(x - h).

In which the directrix is the line x = h - p.

Looking at the graph, we have that:

The vertex is (-2,-2), hence h = k = -2.

The directrix is x = -1, hence -1 = -2 - p -> p = -1.

Thus the equation is:

(y + 2)² = -4(x + 2).

Writing x as a function of y:

B. $x = -\frac{1}{4}(y + 2)^2 - 2$
