Answer:
1
Explanation:
1 because thats The real zeros of a function are the x-values of the points at which the graph intersects the x-axis. Therefore, the zeros are the x-values that make f(x) = 0 true.
The given function is f(x) = -7x + 3.
To determine the real zero of the function, set the function to zero and solve for x.
