always multiplying by 2 (or multiplying by ½ once exponents become negative) and
the only way to get 0 through multiplication is to multiply by 0.A.1.E.10.10TN
Answer to Problem 10:
No, the graph of the function will never intersect the x axis. The values will continue to get smaller in size but never reach zero. The graph will approach 0 as x becomes very small but will never be zero.
Students should be able to identify why this graph
will never intersect the x
axis, i.e., that the function listed
y
= is
