Create the quadratic function that contains the points (0-2), (1, 0) and (3, 10). Show all of your work for full credit.
solniwko [45]

Answer:

My graphing calculator tells me the function is

.. f(x) = x^2 +x -2

_____

Since we recognize the y-intercept as being (0, -2), we only need to find the coefficients of x and x^2.

If you want to do this by hand, you can use

.. y = ax^2 +bx -2

to write 2 equations in a and b for the (x, y) values (1, 0) and (3, 10).

.. 0 = a +b -2

.. 10 = 9a +3b -2

To solve by substitution, you can let a = 2-b, and you have

.. 10 = 9(2 -b) +3b -2

.. 6b = 6 . . . . . . . . . . . add 6b-10

.. b = 1

.. a = 2 -1 = 1

Explan why partoning a directed line segment into a ratio of 1:2 is not the same as finding half the length of the directed in s
lara31 [8.8K]
A ratio of 1:2 means that there are 3 parts in total. One part will be before the desired point, and 2 parts will be after the desired point. This is the same as finding the point that is 1/3 the length. Half the length of the segment would mean there would only be two pieces, each of equal size.

Okay I am trying to help my son. Can someone please help me and explain adding mixed numbers 4 3/10+6 9/10
polet [3.4K]

So when you add mixed numbers, you must convert it into fractions. The four would become part of the fraction and be 43/10 and the six becomes part of the fraction which is 69/10. You can find this by multiplying 4 by the denominator and then adding it to the numerator (4 Times 10 = 40 + 3 = 43/10) and same for the other one. The answer is 112/10, simplify to 11 1/5.

Answer:

x= -2

Step-by-step explanation:

Rational Function can be expressed as:

\displaystyle \large{y =  \frac{a}{p(x - b)}  + q}

Where b is our horizontal shift and q is our vertical shift.

For asymptotes, there are two types which are vertical and horizontal.

Vertical Asymtote is the value of -b itself or x = -b.

Therefore, from the functio:

\displaystyle   \large{y =  \frac{10}{x + 2} }

Our vertical asymtote is x = -2
