Question

WILL MARK BRAINLIEST IF THAT MATTERS
Let’s take our function from before: f(x) = x + 2. Plug in some values for x. f(2) = 4. f(3) = 5. f(4) = 6.

Now we have a set of inputs and outputs for this function. You can write them as a set of ordered pairs, like this: (2, 4), (3, 5), (4, 6).

Like all sets of ordered pairs, these points can be plotted on a graph. If you plot

f(x) = x + 2 and connect the points, you will see that the graph is a straight line. This means that f(x) = x + 2 is a linear function.

Which of these is a set of inputs and outputs for the function f(x) = 2x + 4?

A

(1, 2), (2, 5), (3, 8)

B

(1, 4), (2, 6), (3, 7)

C

(1, 5), (1, 8), (1, 10)

D

(1, 6), (2, 8), (3, 10)

    Answer:

    D

    Step-by-step explanation:

    Plug them in

    Input is the x value, or x, and Output is the y value, or f(x)

    You can figure it out with only the first set of coordinates

    Ima flip the equation around: 2x + 4 = f(x)

    so, substitute x for the x coordinate: 2(1) +4 =f(x) = 2 + 4 = f(x) = 6

    the correct y value when x is equal to 1 is 6, and only D satisfies this rule.

    Hope this helped! 🙂
