Answer:

The given graph shows a function of x.

Step-by-step explanation:

Neither 1 nor 3 is a single-valued relation for some values of x. The graph shown passes the vertical line test, so does represent a function.

The graph is a relation that is a function of x.

___

The attached graph is of the equation of 3. A vertical line will intersect the graph in more than one place, so the relation is NOT a function.

Aidan is paying his taxes and realizes that he was in the first tax bracket (10%) last year. Eleven years ago, he bought a commo

Makovka662 [10]

So let us analyze the given table above. In the first tax bracket, he doesn't have to pay tax on the dividends. The $565 he earned in dividends is not taxable as well. Also the common stock he bought for $705 since this is a long term evidence. So the only taxable would be <span>$780 in coupons on a corporate bond. So multiply this by 10% and you get $78. Therefore, the answer would be the first option. Hope this helps.</span>

Find the y intercept of -2,5 and 3,25

AlexFokin [52]

Answer:

Y-intercept = 13

Step-by-step explanation:

Since, given points are:

(-2,5) and (3,25)

Now, by slope intercept form:

y= mx + b

Here, m= slope and b= y-intercept

In order to find y-intercept, we must find slope firstly:

Since,

Slope= m= y2-y1 / x2-x1

m= 25 - 5 / 3 - (-2)

m= 20 / 5

m= 4

Put ‘m’ in slope intercept form:

y= 4x + b

Substitute either point into above equation:

25= 4(3) +b

25= 12 + b

25 - 12 = b

or b= 25 - 12

b= 13

Hence, y-intercept is 13.
