What is the equation, in standard form, of a parabola that models the values in the table? x~ -1 0 2

Inessa05 [86]

<h2>Steps</h2>

Standard Form Equation: f(x) = ax² + bx + c

So firstly, since (0,5) is one of our values we can plug it into the standard form equation to solve for the c variable (since 0 will cancel out the a and b variable):

$5=a*0^2+b*0+c\\5=c$

Now we know that the value of c is 5. Next, plug in (-1,12) into the standard form equation and simplify (remember to also plug in 5 for the c variable):

$12=a*(-1)^2+b*(-1)+5\\12=a-b+5\\7=a-b$

Next, plug (2,15) into the standard form equation and simplify:

$15=a*2^2+b*2+5\\15=4a+2b+5\\10=4a+2b\\5=2a+b$

Now, with our last two simplified equations we will create a system of equations:

$7=a-b\\5=2a+b$

Now, I will be using the elimination method with this system. With the system, add up the equations together and you will get:

$12=3a$

From here, we can solve for the a variable. With it, just divide both sides by 3:

$4=a$

Now that we know the value of a, plug it into either equation to solve for the b variable:

$7=4-b\\3=-b\\-3=b\\\\5=2(4)+b\\5=8+b\\-3=b$

<h2>Answer</h2>

Putting all of our obtained values together, your final answer is:

$f(x)=4x^2-3x+5$

Need help with this math problem ASAP. Look at the picture attached. The linear function f(x) passes through the points (0,3) an

$f(x) = 2x + 3$

And

$g(x) = 2 \times {3}^{x} \\$

_________________________________

To find the y-intercept of any equation just need to put 0 (( zero )) instead of the x in the equation...

<h2>Let's do it....</h2>

_________________________________

In f ( x ) :

$y - intercept = f(0)$

$f(x) = 2x + 3$

$f(0) = 2(0) + 3$

$f(0) = 3$

Thus :

$y - intercept = 3$

##############################

In g ( x ) :

$y - intercept = g(0)$

$g(x) = 2 \times {3}^{x}$

$g(0) = 2 \times {3}^{0}$

$g(0) = 2 \times 1$

$g(0) = 2$

Thus :

$y - intercept = 2$

_________________________________

The positive difference in the y-intercept value of f ( x ) and g ( x ) is :

$|3 - 2| = |1| = 1$

So write this in the box : 1

And we're done....

Make x the subject of the formula x(a-b)=a(b-x).

ddd [48]

Answer:

Hello,

Step-by-step explanation:

$x(a-b)=a(b-x)\\\\x(a-b)=ab-ax\\\\x(a-b)+ax=ab\\\\x(a-b+a)=ab\\\\x(2a-b)=ab\\\\\\x=\dfrac{ab}{2a-b} \ if\ 2a-b\neq 0$
