Answer 5

Just the answer would be nice!

Answer 6

that's not how I roll, sorry

Answer 7

ok then can u help me learn how to solve it?

Answer 8

ok, f(x) = x+2, or any function, is like saying y = x+2. in other words, in this context, f(x) is the same thing as y. And to find the x-intercept, i.e. the place where the graph hits the x axis, that's where Y = 0. Or, where f(x) is equal to 0. So step 1 is to replace f(x) with 0. What do you get?

Answer 9

?
