Question

Match the function to the graph.

Answer 1

`a) \ sin(x - (\pi )/(2))`

Explanation:

You can does a horizontal shift to the
`sin` function.

• 
  `f(x - c)` shift the graph
  `c` units to the right
• 
  `f(x + c)` shift the graph
  `c` units to the left

Beside we know that when
`sin(0) = -1` then the only option that produce the desire result is the
`a` option because
