Answer:

The graph of f(x) has exactly two x-intercepts not true.

A straight line cannot intersect the x axis twice, so a graph should never have two x-intercepts.

Hope this helps!

Describe how to find the vertex of a parabola if you are given the equation

emmainna [20.7K]

Answer:

The vertex of a parabola is (h,k)

Step-by-step explanation:

The vertex form of a parabola is y=a(x-h)^2+k where a is the stretch/compression factor and (h,k) is the vertex. So to find the vertex, you will need (h,k) which represents the horizontal and vertical shift of the parabola

What is the simplified form of the following expression? 2 startroot 18 endroot 3 startroot 2 endroot startroot 162 endroot

nataly862011 [7]

The simplified form of the provided expression of 2 startroot 18 endroot +3 startroot 2 endroot startroot +162 endroot is 18√2.

<h3>What is the simplified form of an equation?</h3>

The simplified form of an equation is the simplest way of expressing the equation, by applying the required operations of mathematics.

The equation provided in the problem is,

$2\sqrt{18}+3\sqrt{2}+\sqrt{162}$

Let the simplified form of the above expression is <em>n. </em>Thus,

$n=2\sqrt{18}+3\sqrt{2}+\sqrt{162}$

Rewrite the equation to solve it further as,

$n=2\sqrt{3\times3\times2}+3\sqrt{2}+\sqrt{9\times9\times2}\\n=2\sqrt{3^2\times2}+3\sqrt{2}+\sqrt{9^2\times2}$

The square of the term cancel out the square root of it. Thus,

$n=2\times3\sqrt{2}+3\sqrt{2}+9\sqrt{2}\\n=6\sqrt{2}+3\sqrt{2}+9\sqrt{2}\\n=(6+3+9)\sqrt{2}\\n=18\sqrt{2}$

Thus, the simplified form of the provided expression of 2 startroot 18 endroot +3 startroot 2 endroot startroot +162 endroot is 18√2.
