Please help will make brainliest. Write the equation of a line that is parallel to y=9 and that passes through the point (3,-8)

kow [346]

Answer:

y= -8

Step-by-step explanation:

$\frac{y- y1}{x- x1} = \frac{y + 8}{x - 3} = m$

where m is the slope of the line.

m= 0 which is equal to the slope of the line y=9

because both are parallel.

$y + 8 = 0(x - 3)$

$= > y = - 8$

Olin [163]

Answer:

n=-9

Step-by-step explanation:

c is the number in the sequence and n is the number you have to multiply by. If the c is 8 you would do -9 times 8.

Enter the domain and range of the function g(x) = 9x2 − 5 as an inequality, using set notation and using interval notation. Comp

tia_tia [17]

The domain and the range of a function are the set of input and output values, the function can take.

The domain and the range of $g(x) = 9x^2 - 2$ is $(-\infty, \infty)$ .
The parent function $f(x) =x^2$ is vertically compressed by 9, then shifted down by 5 units to get $g(x) = 9x^2 - 2$

Given

$g(x) = 9x^2 - 2$

Domain and range

There is no restriction as to the input and the output of function g(x).

This means that the domain and the range are $(-\infty, \infty)$

$(-\infty, \infty)$ is in interval notation

The corresponding set notation is: $- \infty < x < \infty$

The parent function

We have:

$f(x) = x^2$

First, the parent function is vertically compressed by a factor of 9.

The rule of this transformation is:

$(x,y) \to (x,9y)$

So, we have:

$f'(x) = 9x^2$

Next, the function is shifted down by 5 units.

So, we have:

$g(x) = f'(x) - 5$

$g(x) = 9x^2 - 5$
