Question

Use the cubic model y=10x^3-12x to estimate the value of y when x=3

Answer 1

Y=10(3)^3-12(3)
y=270-36
y=234

Answer 2

Answer:

The value of y = 234 when x = 3.

Step-by-step explanation:

The given model function is y = $10x^3 - 12x$

We need to find the value of y when x = 3.

So, plug in x =3, in the above function, we get

y = $10(3)^3 - 12(3)$

y = 10(27) - 36

y = 270 - 36

y = 234

So, the value of y = 234 when x = 3.
