The height of a saw tooth in inches after time in seconds is represented by the function y = 0.3sin (30x + 1.5) - 0.1 for t > 0. without graphing the function, determine the range that the saw tooth covers.

Range is from -0.4 till 0.2, inclusive

Step-by-step explanation:

y = 0.3sin (30x + 1.5) - 0.1

-1 < sin(x) < 1

-1 < sin(30x + 1.5) < 1

Because this is a change in domain, not in range

-0.3 < 0.3sin(30x + 1.5) < 0.3

-0.3-0.1 < 0.3sin(30x + 1.5) - 0.1 < 0.3-0.1

-0.4 < 0.3sin(30x + 1.5) - 0.1 < 0.2

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
