The value of jon’s stock portfolio is given by the function
v(t) = -3t^2 + 60t + 44
where v is the value of the portfolio in thousands of dollars and t is the time in months. what is the maximum value of jon’s stock portfolio?

$344,000

Step-by-step explanation:

A graphing calculator shows the vertex of the function to be v(10) = 344, corresponding to a value of $344,000.

__

Or, you can put the function in vertex form like this ...

v(t) = -3(t^2 -20t) +44

= -3(t^2 -20t +100) +300 +44 . . . . subtract and add 300

v(t) = -3(t -10)^2 +344 . . . . . . . . . . the vertex is (10, 344)

The maximum value of Jon's stock portfolio is $344,000.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

omg what happend to your question? if you could edit this question i can
