Find the equation, (f(x) = a(x - h)2 + k), for a parabola containing point (2, -1) and having (4, -3) as a vertex. What is the s

postnew [5]

Given that the vertex of the parabola is (4,-3)

The parabola passes through the point (2,-1)

We need to determine the standard form of the equation of the parabola.

Standard form of the equation of the parabola:

The standard form of the equation is $y=a(x-h)^2+k$ where the vertex is (h,k) and a is the constant.

Substituting the vertex (4,-3) in the above equation, we get;

$y=a(x-4)^2-3$ ---------------(1)

Substituting the point (2,-1) in the above equation, we have;

$-1=a(2-4)^2-3$

$-1=a(-2)^2-3$

$-1=4a-3$

$2=4a$

$\frac{1}{2}=a$

Thus, the value of a is $\frac{1}{2}$

Substituting the value of a in the equation (1), we get;

$y=\frac{1}{2}(x-4)^2-3$

Thus, the standard form of the equation of the parabola is $y=\frac{1}{2}(x-4)^2-3$

How do I solve: 22-6x>4

uysha [10]

Answer:

22-6x>4

One solution was found :

x < 3

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

22-6*x-(4)>0

Step-by-step explanation:

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

18 - 6x = -6 • (x - 3)

Equation at the end of step 1 :

Step 2 :

2.1 Divide both sides by -6

Remember to flip the inequality sign:

Solve Basic Inequality :

2.2 Add 3 to both sides

x < 3

Inequality Plot :

2.3 Inequality plot for

-6.000 X + 18.000 < 0

x < 3
