Suppose x and y vary together such that y=2x+11y=2x+11.

  1. Suppose x varies from x=4 to x=11.5x

    1. Over this interval, how much does x change by?

      Δx= 

    2. Over this interval, how much does y change by?

      Δy= 

    3. Over this interval, the change in y is how many times as large as the change in x?

       times as large   

  2. Suppose x varies from x=−5 to =-5.1.

    1. Over this interval, how much does x change by?

      Δx=   

    2. Over this interval, how much does y change by?

      Δy=  

    3. Over this interval, the change in yy is how many times as large as the change in x?

       times as large

Expert Answer

Step 1

We’ll answer the first question since the exact one wasn’t specified. Please submit a new question specifying the one you’d like answered.

a.  x varies from x=4 to x=11.5

So x changes by 11.5-4=7.5

Answer(a): 7.5

Step 2

b. At x=4, y=2(4)+11=8+11=19

At x=11.5 , y=2(11.5)+11=23+11=3...
