Question

m

Answer 1

by the way, those are 3x and 8x, not 3 times 3 or 8 times 2 haha let me know!

Answer 2

\[3x^3 + 8x^2 -x + C = f(x)\]

Answer 3

is this the equation?

Answer 4

if so, remember that if:
\[f(x) = 3x^3 +8x^2-x+C\]
\[f(2) = 3(2)^3 + 8(2)^2 -(2) + C\]

Answer 5

the f(x) comes first. Then, after the "C" it says AND f(2) = 1

Answer 6

the f(2) = 1 is what confuses me..

Answer 7

so:
\[f(2) = 3(2)^3 + 8(2)^2 -(2) + C = 1\]

Answer 8

so:
\[24 + 32 -2 + C = 1\]

Answer 9

now solve for C

Answer 10

Got it! It is -53!
