Describe the graph of y=1/2x-10 -3 comapred to the graph of y= 1/x
saw5 [17]

The parent function is:

$y=\frac{1}{x}

The transformed function is:

$y=\frac{1}{2 x-10}-3

$y=\frac{1}{2(x-5)}-3

$y=\frac{1}{2}\left(\frac{1}{x-5}\right)-3

Comparison of simplified transformed function with the parent function:

  • The function multiplying by a number indicates dilation.
  • The function is being compressed in vertical direction by a factor of 2 if the number lies between 0 and 1.
  • Subtracting a number from x indicates a horizontal shift towards right.
  • That is the parent function is transformed 5 units to right.
  • Subtracting a number from the function indicates a downward shift.
  • That is the parent function is transformed 3 units down.

Hence the graph of y=\frac{1}{2 x-10}-3 is the graph of y=\frac{1}{x} stretched vertically, shifted right by 10 unit and shifted 3 unit down.

The image of the graph is attached below.

Drag the simplified value into the box to match each expression.
Maru [420]

Answer:

The answers are as follows: 12 106 42

Step-by-step explanation:

Given: $ 18 - 4^2 + 5 \times 2 $  

Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate $ 18 - 4^2 $ separately and $ 5 \times 2 $ separately and add them. So we have $ 18 - 16 + 10 = 2 + 10 =12 $.

Now for the second question: $ 9^2 + 4 \times 7 - 3 $. we would get $ 81 + 28 - 3 = 106 $

Next, $ 5^2 - 4 + 7 \times 3 $. This could be written as:  $ 25 - 4 + 21 = 42 $. Hence the answers.
