Answer:

Step-by-step explanation:
So we have the equation:

First, separate the second term:

Let u equal 5ˣ. So:

Combine like terms:

Divide both sides by 6:

Substitute back u:

Take the base 5 logarithm of both sides:

The left cancels:

Evaluate the right:

So, our answer is 2.
And we're done!

Answer:
y = 2 -√(x+1)
Step-by-step explanation:
The square root function is reflected across the x-axis and shifted 1 unit to the left and 2 units up.
y = -√x . . . . . reflects the function across the x-axis
y = -√(x+1) . . . shifts the reflected function 1 unit to the left
y = 2 -√(x +1) . . . shifts the above function 2 units up
The graph is of the equation y = 2 -√(x+1).
-3(x+(3))^2-4 is the answer
