A function is expressed by the equation y=0.3x-6. For what value of the independent variable will the value of the function be equal to - 6; - 3; 0?

0; 10; 20

Step-by-step explanation:

x is the independent variable

y is the dependent variable

y is dependent on x

a) For what value of the independent variable will the value of the function be equal to - 6

y=0.3x-6

-6 = 0.3x-6

0=0.3x

x = 0

Therefore, if the independent variable is 0, the value of the function will be - 6.

b) For what value of the independent variable will the value of the function be equal to - 3

y=0.3x-6

-3 = 0.3x-6

0.3x = - 3+6

0.3x = 3

x = 3/0.3

x = 10

Therefore, if the independent variable is 10, the value of the function will be - 3.

c) For what value of the independent variable will the value of the function be equal to 0.

y=0.3x-6

0=0.3x-6

6 = 0.3x

x = 6/0.3

x = 20

Therefore, if the independent variable is 20, the value of the function will be 0.
