If you have a table that tells you the  (x,y) or coordinates on a graph you can take those coordinates and insert them into the equation y=mx=b. this is the equation to find the slope of a line. If you solve for b in the equation you will have the y intercept. the mx would be the slope.

What is <br> <img src="https://tex.z-dn.net/?f=9%28%20%5Cfrac%7B1%7D%7B3%7D%20%29-4%282.6%29%2B2%28-3%29" id="TexFormula1" title

Hello, that number before the parenthesis means we have to multiply the number outside the parenthesis for the one inside it.

So, the first one 9(1/3) it's easy. We can write 9 as 9/1 to semplify our work.

You have to cross multiply. When cross multiplying, you can simplify numbers. 9 and 3 can be both divided for 3.

You get 3/1 × 1/1 = 3

It equals to 3

Then, 4(2.6) = 4 × 2.6 = 10.4

2(-3) = +2 × (-3) = -6

When you multiply a positive number for a negative one, you'll always get a negative number.

Sum all the results.

3 - 10.4 - 6 = 3 - 10.4 - 6 = - 13,4

Final answer: -13,4

What is the range of the function y= 2sinx​
Nana76 [90]
<h2>Hello!</h2>

The answer is: [-2,2]

<h2>Why?</h2>

The range of a function shows where the function can exist in the y-axis.

To know the range of the function, we have to isolate x,

So

y=2sinx\\\frac{y}{2}=sinx\\ Sin^{-1}(\frac{y}{2}) = x

The only possible values that y can take go from -2 to 2. Taking values out of these values will give as result a non-real number.

Therefore,

The range of  the function is [-2,2]

Have a nice day!
