Find the inverse function of f(t) =t7−5f ( t ) = t ^ { 7 } - 5f(t) =t7−5 .
A) f−1(t) =t−57f ^ { - 1 } ( t ) = \sqrt [ 7 ] { t - 5 }f−1(t) =7t−5
B) f−1(t) =t7−5f ^ { - 1 } ( t ) = \sqrt [ 7 ] { t } - 5f−1(t) =7t−5
C) f−1(t) =t+57f ^ { - 1 } ( t ) = \sqrt [ 7 ] { t + 5 }f−1(t) =7t+5
D) f−1(t) =t7+5f ^ { - 1 } ( t ) = \sqrt [ 7 ] { t } + 5f−1(t) =7t+5
E) The function does not have an inverse.
