Answer :
Let f(x) = \(5x - 4x^2 + 3\)
i)The value of f(x) at x = 0 is :
\( = 5(0) - 4(0)^2 + 3\)
\( = 3 \)
\(\therefore \) f(0) = 3.
ii)The value of f(x) at x = -1 is :
\(= 5(-1) - 4(-1)^2 + 3\)
\( = -5 - 4 + 3 \)
\( = -6 \)
\(\therefore \) f(-1) = -6.
iii)The value of f(x) at x = 2 is :
\( = 5(2) - 4(2)^2 + 3\)
\(= 10 - 16 + 3 \)
\(= -3 \)
\(\therefore \) f(2) = -3.
