Hi I need help with my Calculus assignment

For each of the following functions, use the Horizontal Line Test to determine whether it is one-to-one. A a) The function in graph A is [ Select ]\fb) The function in graph B is [Select ] v C c) The function in graph C is [Select ]\fE o- e) The function in graph E is [ Select ] V3$+1 234' Find the inverse for the function f (3:) 2 Suppose a student writes the following solution. Is it correct? 3$+1 234 Line 1: Write y = and solve for 3:.
