Answer:
f(-x) is a reflection of f(x) in the y-axis
Step-by-step explanation:
–f (x) reflects the function in the x-axis (that is, upside-down). f (–x) reflects the function in the y-axis (that is, swapping the left and right sides).
this makes no sence you said 2x+3=-8 if x =-8 then the answer would be
2x-8+3=-8 ??? that is not correct
