Use an inequality to express the RANGE of the function represented in the graph

Someone this asap for a group of students attends a basketball game. * the group buys x hot dogs at the concession stand for $2 each. * the group buys y drinks at the concession stand for $3 each. the group buys 29 items at the concession stand for a total of $70. how many hot dogs did the group buy?

Which graph represents the function g(x) = |x + 4| + 2?

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?
