Which of the following describes the graph of y = x² - 225?

lara [203]

Answer:

option 4. The graph has zeroes at x = 15 an x = -15 and it opens upward.

Step-by-step explanation:

we have

$y=x^{2} -225$

This is the equation of a vertical parabola open upward (the leading coefficient is positive)

The vertex represent a minimum

The vertex is the point (0,-225)

The axis of symmetry is x=0 (y-axis)

Find the x-intercepts (values of x when the value of y is equal to zero)

For y=0

$0=x^{2} -225\\x^2=225$

square root both sides

$x=\pm15$

therefore

The graph has zeroes at x = 15 an x = -15 and it opens upward.

Amiraneli [1.4K]

Answer:

Following are the responses to the given question:

Step-by-step explanation:

Mean Absolute Deviation MAD

$MAD = \sum_{i=1}^{n} \frac{\left | actual_{i}-forecast_{i} \right |}{n}$

Mean squared error

$MSE=\Sigma^{n}_{i=1} \frac{(Actual_i - Forecast_i)^2}{(n - 1)}$

linear trend equation is $Ft = 124 + 2t$

$MAD = \frac{23}{10} = 2.3\\\\MSE = \frac{91}{9}= 10.11\\\\$

Naive method

$MAD = \frac{36}{9} = 4\\\\MSE = \frac{202}{8}=25.25\\\\MAD (Naive) = 4\\\\MAD (Linear) =2.3\\\\MSE (Naive)=25.25\\\\MSE (Linear)=10.11\\\\$
