Find each function value.g(x)=x

^{3}-2x

(a) *g*(3)= 1 (b) *g*(10)= 2 (c) *g*(-3)= 3 (d) *g*(7)= 4 - Nov 5th 2012, 10:24 AMPaulAdrienMauriceDiracRe: Can anyone help?
To find value of a function at x=a, where a is some constant, you replace every x in that function with a.

$\displaystyle g(x)=x^3-2x$

(a) $\displaystyle g(3)=3^3-2*3=27-6=21.$

(b) $\displaystyle g(10)=10^3-2*10=1000-20=980$.

So your answers are incorrect, but I hope you understand now, can you do rest of the problem (parts (c) and (d))? - Nov 5th 2012, 10:28 AMPetrusRe: Can anyone help?

it's not the same question, and I not looking for answers only, I am trying to really understand it. As for the 1234 numbers, I am not putting those, I think it's a pc error.

you've been given ample instruction in evaluating function values. thread closed.
