How would the domain & range of y= 1/4x-6 be determined !

Step-by-step explanation:

It's an equation of a linear function in the slope-intercept form:

m - slope

b - y-intercept

The domain of any linear function is the set of all real numbers.

The range of any linear function where m ≠ 0 is the set of all real number.

If m = 0, then the equation of a line is y = b. Then the range is {b}.

We have m = 1/4 ≠ 0. Therefore the range is the set of any real numbers.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

don't give

take it once

try and try and you will not

happy to
