Given the equation square root of quantity 2x plus 8 end quantity equals 6, solve for x and identify if it is an extraneous solu
Alex_Xolod [135]

Answer:

Solution: x = 6

Step-by-step explanation:

Given equation is:

\sqrt{2x+8}=6

In order to solve the equation both sides will be squared

(\sqrt{2x+8})^{2} = (6)^2 \\2x+8 = 36\\2x = 36-8\\2x = 28\\x = 14

Verifying the solution

\sqrt{2(14)+8} = 6\\ \sqrt{28+8} = 6\\\sqrt{36} = 6\\6 = 6

What is the equation of the graph????
tia_tia [17]
The graph shown above is a "parabola" and the parent function is x². So, we can start off at x². The graph of x² intersects the x and y-axis at (0, 0). In this case, it's simply being shifted up by 1 and intersects the x and y-axis at (0, 1). Therefore, the equation is:
y = x^2 + 1

To check, let's plug in 0 for x, and see what we get (we should get 1):
y = x^2 + 1
y = 0^2+1 = 0+1=1

We are right, so your final answer is x² + 1.
