Write the equation of the graph

olchik [2.2K]

Answer:

$y = 2.cos(x) - 2$

Step-by-step explanation:

1. Shifting $cos(x)$ right or left, top or down, as the graph in the question has the same illustration of $cos(x)$ . Consider

$y = a.cos(x) + b$

2. find a and b by using two sample points from the graph: $(0, 0)$ and $(\pi, -4)$

$0 = a.cos(0) + b => a + b = 0\\ -4 = a.cos(\pi) + b => b-a=-4\\\left \{ {{2b=-4} \atop {2a=4}} \right.\\a = 2, b=-2\\$

If one of the roots of the quadratice quation x2+kx-12=0is4,what is the value of k?

uysha [10]

<h3>Given Equation:</h3>

$\huge \purple {\rm { {x}^{2} + kx - 12 = 0}}$

<h3>Value:</h3>

$\huge \purple {\rm {x = 4}}$

$\huge \purple {\rm {The \: value \: of \: k.}}$

<h3>Solution:</h3>

$\huge \purple {\rm { {(4)}^{2} + k(4) - 12 = 0}}$

$\huge \purple {\rm {or, \: 16 + 4 k - 12 = 0}}$

$\huge \purple {\rm {or, \: 4k = - 4}}$

$\huge \purple {\rm {or, \: k = \frac{ - 4}{4} = - 1}}$

<h2>Answer:</h2>

$\huge \purple {\sf {The \: value \: of \: k \: is \: -1}}$

Carolyn says that point A and point B represent opposite integers. a. What is the opposite of the integer represent by point A?

zysi [14]

we are given

point-A= -7

point-B=8

(a)

opposite of point-A is negative of point-A value

so,

opposite of point-A is -(-7)

opposite of point-A is 7

opposite of point-B is negative of point-B value

so,

opposite of point-B is -8

opposite of point-B is -8

(b)

we can see that

opposite of point-A is 7

opposite of point-B is -8

they are not equal

so, this argument is FALSE.......Answer
