Answer:

2

Step-by-step explanation:

We need to plot the points in a graph and see the general shape of the curve.

<em>Attached is the graph.</em>

<em />

This Upside Down "U" shaped curve is that of a parabola, which has the general form

ax^2 + bx + c

Thus, we see, the function is a 2nd degree function, highest power is 2.

Answer: The degree of the power is 2.

Step-by-step explanation:

In the table we can see that h(0) = 0, so in our function h(x) there are no term that is not multiplicated by x.

we also have:

h(-2) = -8

h(2) = -8

So we see that the function h(x) is a pair function, so the degree must be a pair degree.

We also see that h(1) = h(-1) = -2

So make sense to think that the function is of the form:

h(x) = a*x^n

and for example:

h(2) = a*(2^n) = -2

where n can be 2 or 4

if n = 4, we have

h(2) = a*(2^4) = a*16 = -2

then a = -1/8

and h(1) = (-1/8)*1^n = -1/8

but we know that h(1) must be equal to -2, so n= 4 is not the correct option.

if n = 2

h(2) = a*(2^2) = -8

a*4 = -8

a = -2

and h(1) = -2*(1^2) = -2

this works.

So the degree power of the function is equal to 2.

Guys plzzz help me i don't know how to figure out this question 10(6x+7)=26
Mekhanik [1.2K]
What is x
First you use distributive property
60x+70=26
Next subtract 70 on both sides which gives you -44
60x=-44
Then you divide 60 into -44 which will give you -1.36__36 is repeathing
so X=-1.36 repeading

Round the following times to 1 decimal place 8.16
Mekhanik [1.2K]
The answer is 8.2 bc anything above a 5 goes up.
8.16 <<< a 6 is greater than 5. So the 1 goes up to a 2.
