Which is the graph of f(x) = -(x + 3)(x + 1)?

Bas_tet [7]

Answer:

See attachment

Step-by-step explanation:

A function is given to us and we need to tell which graph represents the given function. The function given to us is,

$\tt: \implies f(x) = -( x + 3 )( x + 1 )$

Let's find out at which points do the graph Intersects x axis / finding the roots. For that substitute f(x) = 0 , we have ,

$\tt: \implies -(x +3)( x + 1 ) = 0$

Equate each factor by 0 ,

$\tt: \implies \boxed{\blue{ \tt x = -1,-3 }}$

Therefore the graph will intersect x axis at x is equal to -1 and x is equal to -3 .

On looking at the given graphs in the options the second graph intersects x axis at -1 and -3 .

Hence the second option is correct .

How many values of x will satisfy the equation |x-1| = | x+3|

nalin [4]

The value of x that will satisfy the equation is x=-1.

We have given that,

$\left|x-1\right|=\left|x+3\right|$

We have to solve the above inequality

<h3>What is inequality?</h3>

Inequality is a relation that makes a non-equal comparison between two numbers or other mathematical expressions.

Find the positive and negative intervals

$x < -3,\:\:-3\le \:x < 1,\:\:x\ge \:1$

Solve the inequality for each interval

$x < -3,\:\:-3\le \:x < 1,\:\:x\ge \:1$

$\mathrm{No\:Solution}\quad \mathrm{or}\quad \:x=-1$

Therefore we get,

$x=-1$

Find the x-values (if any) at which f is not continuous. which of the discontinuities are removable? (use k as an arbitrary inte

stich3 [128]

Here we are to find the values of x in which the function f (x) = csc 5x is discontinuous. What this usually means is to find when the value approaches infinity.

We know from trigonometric identities that csc is the equivalent to 1 / sin, therefore the function in terms of sin is:

f(x) = 1 / sin 5x

We can see that the function becomes discontinuous when sin 5x = 0, that is a value divided by 0 is discontinuous or approaches infinity.

sin 5x is equal to zero when:

5x = 0 or π

So given k as an arbitrary integer

5x = k π

So k can be: k = 0, 1, 2

x = k π/ 5

Find the value of x in the triangle shown below

Yakvenalex [24]

Use the Pythagorean theorem to find X

A² + B² = C²

X² + 4² = 5²

X² = 5² - 4²

X² = 25 - 16

X² = 9

.: X = 3
