Answer:
8
Step-by-step explanation:
When you are told to find f(-5), that means that you are to sub in a -5 for every x you see. That -5 could be any number or expression. Subbing in a -5 looks like this:
[tex]7(-5)^5+35(-5)^4-2(-5)^3-4(-5)^2+30(-5)+8[/tex]
Be careful with all those negatives. Doing the math on that gives you that f(-5) = 8
