graph and vertex are included

Step-by-step explanation:

To find the answers for the table, you must plug in each x value into the equation and get your y value:

x = -1

(-1^2)-(4*-1)-1

=

1+4-1

=

4

When x = -1, y = 4

x=0

(0^2)-(-4*0)-1

=

-1

When x = 0, y = -1

x = 1

(1^2)-(4-1)-1

=

1-4-1

=

-4

When x = 1, y = -4

x = 2

(2^2)-(4*2)-1

=

4-8-1

=

-5

When x = 2, y = -5

x = 3

(3^2)-(4*3)-1

=

9-12-1

=

-4

When x = 3, y = -4

I made a graph of this shown below.

I also created a table, that answrs your question below.

Hope this helps!

true !

step-by-step explanation:

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:
