Answer:
Chon
Step-by-step explanation:
Step-by-step explanation: Move all terms that don't contain y to the right side and solve.
Exact Form:
Given:
The function is
To find:
The domain, range, and intercepts of the function.
Solution:
We have,
It is a linear function, and domain and range of these types of functions are all real numbers.
Put x=0 in f(x), to find the y-intercept.
So, the y-intercept is 11.
Put f(x)=0 in f(x), to find the x-intercept.
Divide both sides by 7.
So, the x-intercept is .
Therefore, .
