Answer:
the answer is C
Step-by-step explanation:
we will say x will = 1 for the explanation
here max starts at 30 meters and hikes for one hour, in the equation he hikes 10 meters per hour, so x is how many hours he hikes (in this case one) so we multiply 10 by x or 1 and get 10, that's the total amount of climbing he has done
however, remember that he started 30 meters ahead, so we put that in the function as + 30 at the end, saying that whatever the result of the first part, 30 is added to it representing the distance he climbed
i hope this helps, this applies to most functions like this
FUNFACT: the function used here is called a LINIER FUNCTION, its called this because the rate of change is constant, it doesn't vary or waver on a graph, its a straight line (hence the name)
