Look at the diagram, how do you know that y is not directly proportional to x.

lesya [120]

Step-by-step explanation:

If y was directly proportional to x, the graph of y against x would pass through the origin (O).

Since the graph above does not show this, y is not directly proportional to x.

ANYONE GOOD AT MATH?<br><br> PLEASE PLEASE PLEASE SOMEONE HELP ME :(

Mumz [18]

Answer:

The parent function is $f(x)=a(x-h)^{2} +k$

That Parabola's equation is $f(x)=x^{2}$

Step-by-step explanation:

I can't really explain much, but the top equation is a formula for <em>all </em>equations for a parabola. h and k are the x and y-values of the vertex. a is, well, a.

How did I find the equation of the parabola? Simple. Since the vertex is on the origin, h and k are 0. Also, because it intercepts (2,4) and (1,1), a=1.

X^2 + 6x - 18 solve for x

Simora [160]

Answer:

x = - 3 ± √27 or if you want it in decimal form correct to nearest hundredth:

x = -8.20, 2.20.

Step-by-step explanation:

x^2 + 6x - 18 = 0

this will not factor so we use completing the square:

x^2 + 6x = (x + 3)^2 - 9 so:

(x + 3)^2 - 9 - 18 = 0

(x + 3)^2 = 27

x+ 3 = ±√27

x = - 3 ± √27
