You can put this solution on YOUR website!
f%28x%29=x-7x%2B10
I'll do one of these so you can see how it's done and I'll leave the other two to you. Let's take b) f(5):
To find f(5), just plug in 5 everywhere you see x in the equation. Then simplify.
f%285%29=5-7%285%29%2B10
f%285%29=5-35%2B10
highlight%28f%285%29=-20%29
Good Luck,
