Which statement best describes if the relation (c, f) is a function?

The graph is not a function of x because the line x=0 intersects the graph at two points

Step-by-step explanation:

For any function of x, x can only map to one point. What this means is that for every x value, it only results in one y value. If you can input x into the relation's equation and get two outputs, the relation is not a function.

We can check if an x value maps to two points by using a vertical line, such as x=0, and if it crosses the relation at two points, the relation is not a function.

Since x=0 crosses the line at two points, it means that this relation is not a function.

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

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:
