Answer:

draw the points, and then make the x negative if it is reflection over the X axis, y negative if it is aver the y axis, and both if it is a 180 rotation.

for the reflection over y=x, I don't know an easier method so just count the number of units to the line(don't use pythagorean theorem, just go along the lines of the graph, and repeat on the other side.

Given the functions k(x) = 2x2 − 7 and p(x) = x − 4, find (k ∘ p)(x).

Fynjy0 [20]

For this case we have the following functions:

$k (x) = 2x ^ 2-7\\p (x) = x-4$

We must find $(k_ {0} p) (x)$ . By definition of compound functions we have to:

$(k_ {0} p) (x) = k (p (x))$

So:

Taking into account that:

$(a-b) ^ 2 = a ^ 2-2ab + b ^ 2$

Different signs are subtracted and the major sign is placed.

$k (p (x)) = 2 (x-4) ^ 2-7 = 2 (x ^ 2-2 (x) (4) + 4 ^ 2) -7 = 2 (x ^ 2-8x + 16) -7 = 2x ^ 2-16x + 32-7 = 2x ^ 2-16x + 25$

Finally we have to:

$(k_ {o} p) (x) = 2x ^ 2-16x + 25$

Answer:

$(k_ {o} p) (x) = 2x ^ 2-16x + 25$

Source of magnetic force - Nail

Source electric force - battery cell

<h3>What is an electromagnet?</h3>

We know that the electromagnet is a type of magnet whose magnetic property depends on the interaction of the magnetic material with an electric field. We can see in the image that the nail which serves as the magnetic material is connected to a cell which is the source of the given electric current.

It the follows that the nail above is the source of the magnetic force because the coils of wire while the battery cell is the source of the electrical force.
