Find all real zeros of the function y=-5x-7
2 answers:
Answer: The required zero of the given function is x = -1.4.
Step-by-step explanation: We are given to find all the real zeroes of the following function :
Since the given function is linear, so it will have only one real zero.
Also, the zeroes of a function y = f(x) is given by f(x) = 0.
So, the zero of the given function (i) is
Thus, the required zero of the given function is x = -1.4.
