Which set of data points represents an exponential function?

D

Step-by-step explanation:

In the data set in option D, the x-values are equally spaced, (i.e. , however, the x-value are not equally spaced. This rules out the possiblity of the data set in option D being a linear function.

To confirm if it's an exponential function, let's examine if the data set has a "constant multiplying factor", n, that takes us from one y-value to a successive y-value.

Thus:

What do we multiply ⅑ with that will give us the next successive y-value, 1?

Thus, let n be the constant multiplying factor we are looking for.

Therefore:

⅑ × n = 1

Solve for n. Multiply both sides by 9

n = 9.

If we multiply the second y-value which is 9, by 9, wwe will get the next successive y-value, which is 81.

This means the data set has a constant multiplying factor of 9.

Therefore, the data set in option D represents an exponential function.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
