Answer:
one real solution
Explanation:
A "solution" to a function is the input value where the output is zero.
So, we are to solve for the input w in the given equation, and we can make the other side zero by adding 47 to both sides, then square-rooting both sides:
w² - 47 + 47 = 0
w² = 0
√w² = √0
w = 0
Hence, there is one real solution to the equation, which will be at w = 0.
