Mathematics

Kamila [148]3 years ago

Answer:

B or the second option

Step-by-step explanation:

the rules of math state that you must not have a square root in the denominator so in order to get rid of it multiply the top and bottom by the square root on the bottom. Any square root times itself takes away the square root symbol

Which equation has a graph that lies entirely above the x-axis?
kogti [31]

Answer:

Answer:

Option C.

Step-by-step explanation:

The vertex form of a parabola is

where, a is constant, (h,k) is vertex.

If a<0, then it is a downward parabola and if a>0, then it is an upward parabola.  

A downward parabola never lies entirely above the x-axis.

First equation is

It is a downward parabola and vertex is (-7,7).

Second equation is

It is an upward parabola and vertex is (7,-7).

Third equation is

It is an upward parabola and vertex is (7,7).

Fourth equation is

It is a linear equation with y-intercept -7.

Only equation 3 is an upward parabola whose vertex lies above the x-axis.

Marlon and Michelle have to graph a function with the equation y=x2and are having to debate about which is the most important el
Usimov [2.4K]

Answer:

Correct answer is the domain.

Step-by-step explanation:

A domain is the input set of a function.

A range is the output set of the function.

It is more  important to know the domain of the function to be able to determine the corresponding output set so the function can be graphed. To start with the domain is very useful because every domain element has a corresponding unique output element.

Suppose you started with the range element of 9. The input set for an output of 9 is {-3,3}. This makes it hard to match up the elements. This example highlights why it is important to start with the domain rather than the range.
