Question

Evaluate:
f(x) = 2x^5 -3x^4 + x^3 - 6x + 20: x = 2
and
g(x) = -8x^3 + 5x^2 + 14; x = -3

Answer 1

hey man put 2 in place of f(x) & by MDAS rule, try to solve it.
do the same in g(x).
but remember if power is even (-) becomes (+) & vice versa if odd:)

Answer 2

in place of x* in f(x)

Answer 3

ok thanks

Answer 4

one I do for u\[2(2)^5-3(2)^4+2^3-6(2)+20=64-48+8-12+20= u know \it\]
