Answer:
When x = 5, y = 7000 * 5 + 125000 = $160,000.
When x = 10, y = 7000 * 10 + 125000 = $195,000.
To find f(4), you want to substitute x for 4 in the equation. It would look like:
f(4) = 3(4) - 6
Then, just do the math:
f(4) = 12 - 6
f(4) = 6

Let x be the width of the train;
50.6ft =6x-5.8ft <--- solve for x
50.6+5.8=6x
56.4 ft=6x
56.4/6=x
9.4 ft = x
Therefore the width of the train is 9.4 ft
Hope I helped :)
Using the function concept, it is found that the correct option is:
- C. Yes; the graph passes the vertical line test.
- In a function, <u>one value of the input can be related to only one value of the output</u>.
- In a graph, it means that <u>for each value of x(horizontal axis), there can only be one respective value of y(vertical axis)</u>. If it happens, it means that the graph passes the vertical line test.
In this graph, for <u>each value of x, there is only one value of y</u>, hence it passes the <em>vertical line test</em>, and option C is correct.
