5 0

Step-by-step explanation:

If f(x)=3x+2and g(x)=x^2-9

find (f-g)(x)

f(x)- g(x) = [3x + 2] - [x^2 - 9]

= -x^2 + 3x + 11

Given f(x)=6(8-x)+5.<br> What does the notation f(-2) mean?<br> What is the value of f(-2)?
Kitty [74]

Answer:

f(-2) means that x = -2

f(-2) = 65

Step-by-step explanation:

f(x) = 6(8 - x) + 5

f(-2) = 6(8 + 2) + 5

f(-2) = 6(10) +5

f(-2) = 60 + 5

f(-2) = 65

Evaluate √x^2 + y^2 when x^2 =20 and y^2 =10
schepotkina [342]

Answer:

5.477

Step-by-step explanation:

Here we have to get the value √ ( x²+y² ) in this question where the values of x² and y² are given to be 20 and 10 respectively.

Let A = √ ( x²+y² ) =√(20+10) {Since the value of x² =20 and that of y² =10}

⇒ A= √30 =5.477  

Therefore, the value of  √ ( x²+y² ) is 5.477. (Answer)

To shift the graph of an equation a certain number of units _____, you need to subtract that number from the functions equation
FromTheMoon [43]

Answer:

The correct option is A) Down.

Step-by-step explanation:

A function can be shift vertically up or down by adding some positive or negative constant.

For example:

Consider the figure 1:

The function g(x)=f(x)+k shifted up by <em>k</em> unit. (where <em>k</em> is 1 unit)

Now consider the figure 2:

The function g(x)=f(x)-k shifted down by <em>k</em> unit. (where <em>k</em> is 1 unit)

Which means to shift the graph of an equation certain number of units up, we need to add that number from the functions equation.

Similarly, to shift the graph of an equation certain number of units down, we need to subtract that number from the functions equation.

Therefore, the correct option is A) Down.
