2f
f+4(f-2)
To find f(-2), substitute -2 into the function f(x). So, f(-2) = 2(-2)^3 - 2(-2)^2 + 50. Simplifying this expression gives f(-2) = 2(-8) - 2(4) + 50 = -16 - 8 + 50 = 26.
Use the remainder theorem:- f(x) = x3+nx2+3x-5 f(x) becomes f(2) because the divisor is x-2 and 2-2 = 0 f(2) = 8+4n+6-5 = -3 f(2) = 4n+9 = -3 f(2) = 4n = -12 f(2) = n = -3 So the value of n in the expression is -3 Check: f(2) = 8+(4*-3)+6-5 = -3
It is not possible to find the expression of 2y if f(x) = 2x - 3x.

The formula is:K(sp) = [Ca] . [F]2

f+4(f-2)
It is 5*f where f is an expression.
Because f represents a function.
To find f(-2), substitute -2 into the function f(x). So, f(-2) = 2(-2)^3 - 2(-2)^2 + 50. Simplifying this expression gives f(-2) = 2(-8) - 2(4) + 50 = -16 - 8 + 50 = 26.
