7. To furnish the teachers' cafeteria in a school, the director ordered some chairs for 10 000L.L.
each, and some tables for
16 000L.L. each. He paid a total
of 1 880 000 LL. How many
chairs and how many tables did he
order if the number of chairs exceeds the number
of tables by five? ​

pay subcription to get good answer

f(x)=(x+1)^2-2 is the minimum and g(x)=-(x-2)^2+1 is the maximum

Step-by-step explanation:

Looking at the graph, (you should be able to graph this) the parabola for f(x)=(x+1)^2-2 is pointing downwards and stops at the vertex. This vertex is negative which is the lowest point possible which makes it the minimum. The parabola for -(x-2)^2+1 is pointing upwards and stops at the vertex which is the highest point possible which makes it the maximum.
