Question:

Solution:

Let the function

y=f(x)\text{ = }\sqrt[]{x}-9

Now remember the following rule:

To graph y = f(cx)

if 0 < c < 1 , stretch the graph of y = f(x) horizontally by a factor of 1/c.

Thus, applying this to the given function, with c = 3, we can conclude that the correct answer is:

y=f(x)\text{ = }\sqrt[]{\frac{1}{3}x}-9

Which system of equations can be graphed to find the solution(s) to 4x2 = x2 – 7?
Usimov [2.4K]

4x^2 = x^2 - 7

In order to find the solution by graphing we need to make two equation with x and y terms

we use Left hand side 4x^2 for first equation and right side x^2 -7 for second equation.

So the equation becomes

first equation y=4x^2

Second equation y= x^2 - 7

y= x^2 \ and \ y= x^2-7 are the system of equations that can be graphed to find solution
