Which equation represents a quadratic function?<br> y = x2<br> y = 2x<br><br> y =1/x^2

ehidna [41]

Answer:

y = x²

Step-by-step explanation:

A quadratic function is a polynomial function that has a variable to the power of 2 as the highest degree term. y = 1/x^2 is not a polynomial. y=2x is a linear function.

y = x^2 is a quadratic function

The domain of this function is {-12,-6,3,15}. Y=-2/3x+7

Evgen [1.6K]

Considering the given function, the table is completed as follows:

x|y

-12|15

-6| 11

3|5

15|-3

<h3>Which is the function?</h3>

The function is defined by:

$y = -\frac{2}{3}x + 7$

Hence, when x = -12:

$y = -\frac{2}{3}(-12) + 7 = 15$

When x = -6:

$y = -\frac{2}{3}(-6) + 7 = 11$

When x = 3:

$y = -\frac{2}{3}(3) + 7 = 5$

When x = 15:

$y = -\frac{2}{3}(15) + 7 = -3$

Step-by-step explanation:

i = interest 3% for 30 years

This is a simple dynamical system for whom the the solutions are given as

$S=R[\frac{(i+1)^n-1}{i}](i+1)$

putting values we get

S=2000[\frac{(1.03)^{30}-1}{0.03}](1.03)

= $98005.35

withdrawal of money takes place from one year after last payment

To determine the result we use the present value formula of an annuity date

$P = R\frac{1-(1+i)^{-n}}{i}{i+1}$

we need to calculate R so putting the values and solving for R we get

R= $6542.2356
