Find the range of the function for the given domain.

Mathematics

slavikrds [6]3 years ago

Answer:

{-14,-5,-2,10}

Step-by-step explanation:

The given function is

f(x)=3x-5

We need to find the function of the given domain.

The given domain of the function is {-3,0,1,5}.

Substitute x=-3 in the given function.

f(-3)=3(-3)-5\Rightarrow -9-5=-14

Substitute x=0 in the given function.

f(0)=3(0)-5\Rightarrow 0-5=-5

Substitute x=1 in the given function.

f(1)=3(1)-5\Rightarrow 3-5=-2

Substitute x=5 in the given function.

f(5)=3(5)-5\Rightarrow 15-5=10

Therefore, the range of the function for given domain is {-14,-5,-2,10}.

You need to evaluate the function at the given points:

\begin{array}{c|c}x&f(x)\\-3&-14\\0&-5\\1&-2\\5&10\end{array}

So, the range is

\{-14,-5,-2,10\}

Which one is bigger 30% or 4 /15<br>???
Nikolay [14]
I believe 30% is bigger than \frac{4}{15}.

To find the answer, you'd have to convert both the fraction and the percent into decimal form to see which one is truly bigger. Converting the percent is fairly easy. 30% would become 0.30 is decimal form. To find the fraction in decimal form, you'd have to divide the numerator by the denominator, which would be 4 ÷ 15, which makes : 2.6666666666666666666666667. 

Now you compare easily. Which one is bigger? 2.666666666666666666666667 or 0.30? 

0.30 is bigger. So 30% is bigger out of both of them.

Need help with 13 and 14
Svetach [21]

Answer:

13. A

14. C.

Step-by-step explanation:

A relation is a function if there is only one y assigned to each x.

That is if you have a set of points, there should be no repeated x value.

So looking at {(0,0),(-2,4),(-2,-4),(-3,7)} this is not a function because you have two x's that are the same. A.

The slope-intercept form of a linear equation is y=mx+b where m is the slope and b is the y-intercept.

The y-intercept is where the graph goes through the y-axis at.  It goes through at -1 so b=-1.

The slope is rise/run.  So starting from the y-intercept (0,-1) we need to find another point to count the rise & run to... How about (3,1)? That works.  You can do the counting if you want. You could also use the slope formula.

To use the slope formula, I just like to line the points up vertically and subtract vertically then put 2nd difference over the 1st difference.

(0,-1)

-(3,1)

--------

-3  -2

So the slope is -2/-3 or just 2/3.

So the equation is y=2/3 x-1

C.
