Question

Decide whether the function is one-to-one.y = 4(x + 1)2 - 6

Answer 1

Step 1:

A one-to-one function is a function of which the answers never repeat. For example, the function f(x) = x + 1 is a one-to-one function because it produces a different answer for every input.

Step 2:

Write the function

$y=4(x+1)^2\text{ - 6}$

Step 3:

The function is one-to-one because every input produce different outputs,
