Question

What is the value of f(2) for f(x)=2x5−8x4+3x3−4x2+9x−1?

can i get a step by step on this? my final answer was like -1000000 range lmfao

Answer 1

sorry that formatted wrong, there is an exponent at the end of each thing. for instance, 2x^5, 8x^4 and so on. not for 1 tho

Answer 2

ok, so you want
f(x)=2x^5−8x^4+3x^3−4x^2+9x−1
then f(2) = 2(2^5) - 8(2^4) + 3(2^3) - 4(2^2) + 9(2) - 1
= 2(32) - 8(16) + 3(8) - 4(4) + 18 - 1
= ..... finish it please

a final answer of of around -1000000 makes no sense at all
