Step-by-step explanation:
a)
For each value of x, we need to solve for y.
Our equation is x² -2. This means that we multiply x by itself ( x * x = x²), and then subtract that value by 2.
Here is a list of the unfilled answers:
x = -2:
-2²-2 = -2 * -2 -2 = 4-2 = 2. -2 * -2 = 4 because two negatives multiplied together makes a positive.
x=-1:
-1²-2 = 1 -2 = -1
x=1
1²-2 = 1-2= -1
x=3:
3²-2 = 9-2 = 7
b)
In this graph, the y represents the vertical part and x represents the horizontal. For each value of y, there is a horizontal line that can be drawn. For example, when y=0, the bolded horizontal line near the bottom of the graph represents that. We then need to find the points on the line representing x²-2 where it touches the horizontal line of y=0. This happens when x=-1.5 and x=1.5, as it is between the positive/negative 1 and 2 values of x
Answer:
The movement produces oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of light energy called a photon. ... Magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave.

Answer:
$7.50
Step-by-step explanation:
<u>If she is not a member:</u>
to print 350 pictures, she will pay 0.2 * 350 = $70
<u>If she IS a member:</u>
to print 350 pictures, she will pay 0.15(350) + 10 = $62.5
THus, the amount she saves is 70 - 62.5 = $7.50
