The graph of y=x^2 is shown below. which of the following could be the graph of y=x^2-3
Xelga [282]
<h2>The graph is given below.</h2>

Step-by-step explanation:

We need to find graph of y = x² - 3

At x = 0 we have

       y = 0² - 3 = -3    

So (0,-3) is a point on the graph.

When y = 0

      0 = x² - 3

       x = 1.732 and -1.732

So, (1.732,0) and (-1.732,0) are the points on the curve.

All these points are satisfied by the graph given below.

A direct variation function contains the points (–9, –3) and (–12, –4). Which equation represents the function?
katen-ka-za [31]

Answer:

\displaystyle y = \frac{1}{3}x

Step-by-step explanation:

First, find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:

\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{3 - 4}{9 - 12} = \frac{1}{3}

Then plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope</em><em> </em><em>Formula</em><em> </em>since you get it done much swiftly that way. It does not matter which ordered pair you choose:

−4 = ⅓[−12] + b

−4

\displaystyle ±0 = b \\ \\ y = \frac{1}{3}x

_______________________________________________

−3 = ⅓[−9] + b

−3

\displaystyle ±0 = b \\ \\ y = \frac{1}{3}x

**You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

I am joyous to assist you anytime.
