Final answer:
If the function f(x) is even and we know one point (3, -4) on the function, we can determine another point (-3, -4) on the function due to its symmetry about the y-axis.
Step-by-step explanation:
If the function f(x) is known to be an even function and we are given the solution point (3, -4) on f(x), we can determine another point on the function. Since f(x) is even, it exhibits symmetry about the y-axis. This means that if the point (3, -4) lies on the function, the point (-3, -4) will also lie on the function.
