F(x)=x+c, where c is an arbitrary constant.
if c is positive then translation above 
if c is negative then translation down
reflection of f(x)=x^2 across x-axis then 
f(x)=-x^2

Write the equation of the graphed in NO SPACES ALL LOWERCASE<br> Help !!
cupoosta [38]

Answer:

The equation of the graphed line is:

  • y = 2

Step-by-step explanation:

From the graph, it is clear that the line is a horizontal line at y = 2.

We know that a horizontal line has a slope of 0 because the value of y does not change no matter what the value of x we put in.

In other words, the equation of the horizontal line would always get the form:

y = k

where k is the y-intercept of the line.

Determining the y-intercept of the line:

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 2

Thus, the y-intercept k = 2

Thus, if we substitute the y-intercept k = 2 in the equation y = k, we get the equation

y = 2

Therefore, the equation of the graphed line is:

  • y = 2

I BET NO ONE KNOWS THIS y varies jointly as x and z. y=20 when x=2 and z=5 . Find y when x=3 and z=6
Greeley [361]

Hello!

If y varies jointly with x and z, it'll mean that x and z are being multiplied by a factor "k", to equal y.

To give you a visual, this is what I mean.

y=kxz

That means we'll want to find k with the first point we're given: (2,20,5)

20=k(2)(5)

20=10k

k=2

Which means our equation is:

y=2xz

Now, let's plug in the x and z from the other point to find y.

y=2(3)(6)

y=36

Hope this helps!
