consider the function f(x) = x2 2x – 15. what are the x-intercepts of the function? left-most x-intercept: ( , 0) right-most x-i

eimsori [14]

we have

$f(x)=x^{2} +2x-15$

we know that

The x-intercept is the value of x when the value of the function is equal to zero

in this problem

Find the roots of the function

equate the function to zero

$x^{2} +2x-15=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$x^{2} +2x=15$

Complete the square. Remember to balance the equation by adding the same constants to each side

$x^{2} +2x+1=15+1$

$x^{2} +2x+1=16$

Rewrite as perfect squares

$(x+1)^{2}=16$

Square root both sides

$(x+1)=(+/-)\sqrt{16}$

$(x+1)=(+/-)4$

$x=-1(+/-)4$

$x1=-1+4=3$

$x2=-1-4=-5$

$x^{2} +2x-15=(x-3)(x+5)$

therefore

<u>the answer is</u>

the x-intercepts are the points $(3,0)$ and $(-5,0)$

Which of the following best defines 2 2/3?

inna [77]

Answer:

A. $\sqrt[3]{4}$ = Cube root of 4.

Step-by-step explanation:

We have been given an expression $2^{\frac{2}{3}}$ . We are asked to find the equivalent expression for our given expression.

Using exponent property $\sqrt[n]{a^m} =a^{\frac{m}{n}$ , we will get,

$2^{\frac{2}{3}}=\sqrt[3]{2^2}$

$2^{\frac{2}{3}}=\sqrt[3]{4}$

Upon looking at our given choices, we can see that option A is the correct choice.
