(9q) find the domain and range of f(x) = = -2x + 3 | 3 sin x |

Option A

Domain = Range = (-∞,∞)

Step-by-step explanation:

We can easily solve this question by using a graphing calculator or any plotting tool.

The function is

f(x) = -2x + | 3 sin(x) |

Which can be seen in the picture below

We can notice that f(x) is a line with periodical ups and downs thanks to the sinusoidal term, but there are no restrictions over the domaoin or range of the function.

It can take any real value as an input, and can produce any real value as an output

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

1/4 because there is 4 grades.
