Each correct answer will receive 2 credits. ... Use this space for ... 5 which point is not on the graph represented by y = x* + 3x – 6? ... The functions are modeled by C(x) = 300x + 250 and ... 11 Let f be a function such that f(x) = 2x – 4 is defined on the domain .... to find B, her account balance after t years.

Answer 2

$5000

Explanation:

We have been given that Juan’s investment account can be modeled by the function,
`C(x)=3x^2-2x+5`

In order to find Juan's initial investment, we substitute x = 0

On substituting x=0 in the given model,

`C(0)=3(0)^2-2(0)+5\\\\C(0)=5`

Now, it has been given that investment is in thousands of dollars.

And we got C(0) = 5.

Therefore, the initial investment was $5000
