It’s axes I’m pretty sure good luck
The answer
the main rule for a square root calculus is given by √A*√B = √A*B, for all value positive of A and B
so we can extended the given value of the fonction as
√x-7 *√x+1 = √x-7 *√x+1 = √(x-7 )* (x+1)
but the extended form of (x-7 )* (x+1) is (x-7 )* (x+1) = x² + x -7x -7= x²-6x -7
therefore, √(x-7 )* (x+1) = √(x²-6x -7), the value which is equivalent to the radical expression is B)√x^2-6x-7, <span>when x≥7</span>
Answer:
what is your question.. if any problems then I will try to solve if I know.
Answer:
B. Yes, because it passes the vertical line test.
Step-by-step explanation:
Vertical line test - if a vertical line passes through more than one pone, the relation is not a function
Any vertical line will only pass through one point, so this relation is a function
The relation is a function because it passes the vertical line test
