f(x)=5x+2
fx=5x1 / 9
29
f(x) = x2 + 5x + 6At a critical point, f'(x) = 0.f'(x) = 2x + 5 = 02x = -5x = -2.5f(-2.5) = (-2.5)2 + 5(-2.5) + 6 = (6.25) - (7.5) + (6) = 4.75
5x lolzz 8)
If you are talking about f(x) then yes it is the same as y
please elaborate your question
y = 3x + 2x^2 + k where k is any number
False
x = ¼x^4 + 4x + k where k can be any number
B- It is a many-to-one function
