What is the domain of the function y=-4x-1 when the range is -25

1 answer:

5 0

y = -4x - 1

It is a linear function different from the constant function. Therefore, if the range is only one number, then the domain is only one number too.

Let's calculate it:

y = -25 → -4x - 1 = -25 |add 1 to both sides

-4x = -24 |divide both sides by (-4)

x = 6

Answer: The domain = {6}.

Write the equation of the circle centered at (0,1) with radius 15.

NNADVOKAT [17]

Answer:

$x^2+(y-1)^2=225$

Step-by-step explanation:

we know that

The equation of the circle in center radius form is equal to

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

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have

$(h,k)=(0,1)\\r=15\ units$

substitute

$(x-0)^2+(y-1)^2=15^2$

$x^2+(y-1)^2=225$
