How do you find the equation of a parabola given two x intercepts

1 answer:

4 0

Let's assume that the parabola has the following intersections with the x axis:
x1 = p
x2 = q
To find the equation of the parabola, we write the following product of binomials:
(x-p) (x-q) = 0
Where,
p, q: intersections with the x axis.
When developing the product of binomials, we obtain the equation of the parabola.
Answer:
(x-p) (x-q) = 0

Step-by-step explanation:

For this, you need to solve a proportion-

3.4 x

----- = -----

1.8 39.75

3.4*39.75=135.15

135.15/1.8= 75.0833.....

The sum of three odd consecutive numbers is fifty-one. What are the numbers?

Fantom [35]

Answer:

15,17,19

Step-by-step explanation:

Make an equation : $x+(x+2)+(x+4)=51$

Solve the equation: $3x+6=51$

$3x=51-6$

$3x=45$

$x=15$

Since x=15 then the second number is 17 and then 19

Answer:

C - The relationship represents a function because each input gives one unique output.

Step-by-step explanation:

To see if it is a function we can do the line test where we have a vertical line and "drag" it along the line. As long as it only hits the line once in every situation it is a function! We can see this passes and therefore the answer is c.

(why is it not d? you can have a non-linear line, but still have a function)
