What is the constant of variation for the quadratic variation? x=2,3,4,5,6 y= 32,72,128,200,288

Bad White [126]

Hello,
y=a*x² ==>
32=a*2²==>a=32/4=8
72=a*3²==>a=72/9=8
128=a*4²==>a=128/16=8
200=a*5²==>a=200/25=8
288=a*6²==>a=288/36=8

Given that fx=2x2-4x+1, then f(-1)is.

oksian1 [2.3K]

Answer:

$f(-1)=7$

Step-by-step explanation:

I am going to assume your question meant the equation

$f(x)=2x^{2} -4x+1$

So $f(-1)$ can be found by substituting all the x terms in the equation with -1

$f(-1)=2(-1)^{2} -4(-1)+1$

And simplifying for our answer

$f(-1)=2(1)+4+1$

$f(-1) = 2+4+1$

$f(-1)=7$

The graph of g(x) resembles the graph of f(x)=x^2, but it has been changed. Which of these is the equation of g(x)?

siniylev [52]

Answer:

Step-by-step explanation:

Anwer A has the following equation:

$g(x)=\frac{3}{5}x^2-3$

In this equation, we can calculated the intercept replacing x by 0, as:

$g(x)=\frac{3}{5}0^2-3=-3$

if this is the answer, the graph of g(x) should be through the point (0,-3) and that happens.

Additionally, the roots of the equations are calculated replacing g(x) by 0 and solving for x, so:

$0=\frac{3}{5}x^2-3\\x_1=\sqrt{5}=2.236\\x_2=-\sqrt{5}=-2.236$

It means that the graph of g(x) should be through the points (2.236,0) and (-2.236,0) and that happens too.

So, the answer is A, $g(x)=\frac{3}{5}x^2-3$
