options: Understand the inverse relationship between exponents and logarithms and use this relationship to solve problems involving logarithms and exponents.

Identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them.

Find inverse functions.
problem_activity: Task
The table below shows some input-output pairs of two functions $f$ and $g$ that agree for the values that are given but some of their output values are missing.
{"table": [{"tbody": [{"tr": [{"th": [{"_value": "$t$"}], "td": [{"_value": "0"}, {"_value": "15"}, {"_value": "30"}, {"_value": "45"}, {"_value": "60"}, {"_value": "75"}, {"_value": "90"}, {"_value": "105"}, {"_value": "120"}]}, {"th": [{"_value": "$f(t)$"}], "td": [{"_value": "0"}, {"_value": "0.5"}, {}, {"_value": "1.3"}, {"_value": "2"}, {"_value": "2.7"}, {}, {"_value": "4"}, {}]}, {"th": [{"_value": "$g(t)$"}], "td": [{"_value": "0"}, {"_value": "0.5"}, {}, {"_value": "1.3"}, {"_value": "2"}, {"_value": "2.7"}, {}, {"_value": "4"}, {}]}]}]}]}
Complete the table in a way so that $f$ could be invertible and so that $g$ is definitely not invertible.
Graph both functions and explain from the graph why $f$ is invertible and $g$ is not.
Come up with two real life situations that $f$ and $g$ could be representing.
Find and interpret the value $f^{-1}(4)$ in terms of these contexts.
