Which of the following could be the equation of the function below? y=0.5cos(2(x-pi/2))+2 y=0.5cos(4(pi/2))-2 y=0.5cos(4(x+pi))+2 y=0.5cos(2(x-pi))-2

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

combine all like terms then its just a 2 step equation

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors

=

x=0.8898305 is the answer to that equation
