Plz for the function f defined by f(x)=x2−2x+4, find f(2b−1).

So firstly, replace x with 2b-1:

Next, do the multiplications and the exponents:

Next, combine like terms and your answer will be:

43

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
