Answer:example, the shadow of -4 from f(x)=-4x-8 is...
Step-by-step explanation:
Change x with -4, so f(-4)=-4(-4)-8. f(-4)=16-8. f(-4)=8. As you may know, f(x) is equal to y. So y=8 or f(-4)=8. Is this what you mean? Let me know if i answer your question.
NyxFur:
Oh okay! So f(-2) would be -2 on the X axis, which looking at the graph would mean that the Y axis would be -4 right?
Yes, f(x) is equal to y.
