Step-by-step explanation:
We know the definition of both functions: , and
A) In order to evaluate what , let's first investigate what g(-1) is using the definition for this function:
Now let's find what f(2) is using f(x) definition:
B) In order to evaluate what , let's first investigate what f(3) is using the definition for this function:
Now let's find what g(7) is using the definition for this function:
Answer:
The y-intercept of the line that passes through the point (3, -6) and which has a slope of 4 is -18.
Step-by-step explanation:
We represent the straight line by using this formula from Analytical Geometry:
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- y-Intercept, dimensionless.
Now we clear the y-intercept:
If we know that ,
and
, the y-intercept of the line is:
The y-intercept of the line that passes through the point (3, -6) and which has a slope of 4 is -18.
