The number in the parenthesis is the X value and they are looking for what the Y value is at that specific X.

So when you look at f(-2), find the Y value where the line crosses.

At X-2, the line crosses Y at -2

At X = 2, the line crosses at Y = 2

At X = 4, the line crosses at Y = 1

The answer is -2,2,1

A small company has 10,000 shares. Stephen owns 500 of these shares. The company decides to split its shares. What is Stephen's

Sergeu [11.5K]

So the company splits there shares now every thing doubles now there are 20,000 shares and you own 1,000 to find the answer you divide a

1,000 by 20,000 which will give you 0.05 then you multiply

0.05 by 100 and you get 5

So after the split you own 5% of the company

A car travels 43 km in 56 minutes.

patriot [66]

Answer:

$\displaystyle v=46.07\ Km/h$

Step-by-step explanation:

<u>Speed</u>

The speed is the ratio between the distance x traveled by an object and the time t taken.

$\displaystyle v=\frac{x}{t}$

The car travels x=43 Km in t=56 minutes. We are required to express the speed in Km/h. The time needs to be expressed in hours:

$t = 56 / 60 = 0.933\ h$

Now apply the formula:

$\boxed{\displaystyle v=\frac{43}{0.933}=46.07\ Km/h}$

Find the difference of functions at x= - 3, (g - f)(-3), given f(x) and g(x): g(x) = x^2−15, and f(x) =2x

FrozenT [24]

Answer:

Step-by-step explanation:

Solution:-

We are given two functions as follows:

$f ( x ) = x^2 - 15\\\\g ( x ) = 2x$

We need to determine the composite function defined as ( g - f ) ( x ). To determine this function we need to make sure that both function exist for all real positive value of x.

The function f ( x ) is a quadratic function which has real values for all values of x. Similarly, function g ( x ) is a linear line that starts from the origin. Hence, both functions are defined over the domain ( -∞, ∞ )

We will perform arithmetic operation of subtracting function f ( x ) from g ( x ) as follows:

$[ g - f ] ( x ) = g ( x ) - f ( x )\\\\\\( g - f ) ( x ) = x^2 - 15 - 2x\\\\$

Now evaluate the above determined function at x = -3 as follows:

$( g - f ) ( -3 ) = ( -3 )^2 - 2 ( -3 ) - 15\\\\( g - f ) ( -3 ) = 9 + 6 - 15\\\\( g - f ) ( -3 ) = 0$
