What is the domain of the function y= square root x?

Mathematics
1 answer:
Goryan [66]3 years ago
5 0

The domain of a function is the set of values of the independent variable for which the function is defined. The square root function is defined for all non-negative real numbers. So, ...

The domain of

 y = √x

is all real numbers greater than or equal to zero. (x ≥ 0)

_____

In some cases, there may be other limits on the domain of a function. A function may be defined for all values of mass, for example, but is of no practical use for values of mass greater than the mass of the known universe (or planet Earth, perhaps).

Someone help please i am so bad at point slope stuff
Fynjy0 [20]
<span>1) Write the point-slope form of the equation of the horizontal line that passes through the point (2, 1). y = 1/2x

2)Write the point-slope form of the equation of the line that passes through the points (6, -9) and (7, 1). 
m = (-9 - 1) / (6 - 7) = -10/-1 = 10
y + 9 = 10 (x - 6)
y = 10x - 69

3) A line passes through the point (-6, 6) and (-6, 2). In two or more complete sentences, explain why it is not possible to write the equation of the given line in the traditional version of the point-slope form of a line. 

4)Write the point-slope form of the equation of the line that passes through the points (-3, 5) and (-1, 4).
m = (5 - 4) / (-3 - -1) = 1/-2
y - 5 = (-1/2) (x +3)
y = (-1/2)x + 7/2

5) Write the point-slope form of the equation of the line that passes through the points (6, 6) and (-6, 1).
m = (6-1)/(6 - -6) = 5 / 12
y - 6 = (5/12) (x-6)
y = (5/12)x + 17 / 2

6) Write the point-slope form of the equation of the line that passes through the points (-8, 2) and (1, -4).
m = (2 - -4)  / (-8 -1) = 6 / -7
y - 2 = (-6/7) (x + 8)
y = (-6/7)x - 50 / 7


7) Write the point-slope form of the equation of the line that passes through the points (5, -9) and (-6, 1).
m = (-9 - 1) / (5 - -6) = -10 / 11
y + 9 = (-10 / 11) (x - 5)
y = (-10 / 11)x -49/11

Im getting brain damage doing this question pls help
EastWind [94]

Answer:

See below and attachment

Step-by-step explanation:

<u>Given function:</u>

  • y = -2(x - 3)² + 4

<em>The graph is attached and the axis of symmetry and all the required points plotted </em>

a) Axis of symmetry:

  • x = 3

b) It has no minimum as the leading coefficient is negative.

  • Maximum value is at vertex- the point (3, 4).
  • Maximum value is y = 4

c) and d) x - and y - intercepts already given in the question

e) Domain is all real numbers. x = ( -∞, +∞ )

Range is y = ( - ∞, 4]

Andreas93 [3]

Answer:

Mariah

Step-by-step explanation:

If you divide 8/10 you get .8 move the decimal 2 times to the left and you get 80%.

Then you divide 36/40 and get .9 move the decimal 2 times to the left and you get 90%
