Question

For the function y = f(x), what is the ordered pair for the point on the graph when x = 3n - 4?

(3n - 4, f(n))

(3n - 4, f(3n - 4))

(x, f(3n))

(x, 3n - 4)

Answer 2

\[\Large\rm (\color{royalblue}{x},\color{orangered}{y})\]\[\Large\rm \color{orangered}{y}=f(\color{royalblue}{x})\]Let's look at an example really quick.

If I plug in 4 for x,

Answer 3

\[\Large\rm \color{orangered}{y}=f(\color{royalblue}{4})\]Then my y value is f(4), yes?

Answer 4

\[\Large\rm (\color{royalblue}{4},~\color{orangered}{f(4)})\]Is how we would write that ordered pair.

Answer 5

Is it B?

Answer 6

So if we're evaluating the function at \(\Large\rm \color{royalblue}{x=3n-4}\),
what do you think our y-value will be?

Answer 7

Yesss, very good!

Answer 8

Choose the slope-intercept equation of the line that passes through the point (6, 4) and is parallel to y = one thirdx - 3.

Answer 9

y = 3x - 14

y = one thirdx + 2

y = -3x + 22

y = -one thirdx + 8
