Well, 27 = 9*3, and mod 26 leaves a remainder of 1, so $n=3$ is a solution.

What is the factorization???

Sav [38]

we can see that

the above curve is parabola

so, firstly , we can find vertex

vertex is (4,0)

$(h,k)=(4,0)$

now, we can use vertex formula of parabola

$y=(x-h)^2+k$

we can plug h and k

and we get

$y=(x-4)^2+0$

so, we can factor it as

$y=(x-4)(x-4)$ ............Answer

Graph each absolute value function. State the domain, range, and y-intercept.

Inessa05 [86]

Answer:

i. D:All real numbers

ii.R: $y\le-2$

iii. Y-int: $b=-2.5$

Step-by-step explanation:

The given function is

$y=-\frac{1}{2} |x-1|-2$

The domain of this function are the values of x that makes the function defined.

The absolute value function is defined for all real values.

The domain is all real numbers.

ii. The range refers to the values of y for which x is defined.

$y=-\frac{1}{2} |x-1|-2$

The vertex of this function is

$(1,-2)$

The function is reflected in the x-axis.

The vertex is therefore the maximum point on the graph of the function.

The range is therefore;

$y\le-2$

Or

$(-\infty,2]$

iii. To find the y-intercept, we substitute $x=0$ into the funtion.

$y=-\frac{1}{2} |0-1|-2$

$y=-\frac{1}{2} (1)-2$

$y=-2.5$

The y-intercept is $b=-2.5$

The graph is shown in the attachment.
