Question

PLEASE HELp PLEASE

Given f(x)= 2/3 x - 1 , complete Parts A and B.



Part A: Using the table provided, create five points to demonstrate that for the function , there is exactly one output value for each corresponding input value. In your final answer, include all calculations and the completed table.







Part B: On a separate sheet of paper, use the points created in Part A to graph the function . Label the values on the - and -axes, and all points on the graph.

Answer 1

x values: 2, 3, 4, 6

y values: 1.4, 2, 2.7, 3.4, 4

f(2)=2/3(2)

f(3)=2/3(3)

f(4)=2/3(4)

f(5)=2/3(5)

f(6)=2/3(5)

Answer 2

Part A. For x, we’ll use 1, 2, 3, 4, and 5. Now, we have to plug in the x-values to get f(x) (or y). I’ll do the first two w/ explanations then just give the answers. when x= 1, f(1)= 2/3•1-1. solve accordingly, you get -0.3. Next, when x= 2, f(2)= 2/3•2-1. Solve and you get f(2)= 0.3. when completing and solving for the other 3 x-values, use the same process and plug into the chart with corresponding numbers. A calculator may be helpful.

Part B. Just graph, use the x-values for x and the y-values for y. if u don’t know how to graph u may want to look back on some of your lessons if available.

Thanks.
