The standard equation of a circle with center C(a, b) and radius r is given by:

thus for C(a, b)=C(7, 5) and radius r=4, the equation is given by:

Answer:
Answer:
F(2b-1) = 4b² - 6b + 4
Step-by-step explanation:
Replace all the x with 2b-1
F(x) = x² - 2x + 4
F(2b-1) = (2b-1)² - 2(b) + 4
= 4b² - 4b + 1 - 2b + 4
= 4b² - 6b + 4
Answer:
Since it is a linear function, it is a directly proportional function
