Find the intervals over which the function is constant.

i think it's a.

(-∞,-2)

Step-by-step explanation:

See the graph attached to this question.

The value of f(x) is constant for the part of the graph which is at the leftmost.  

The values of x for which the function f(x) is constant that we have to determine.

From the graph, it is clear that for x < 2 ( but not including 2) the function is constant.

Therefore, the required interval of x is (-∞,-2) (Answer)

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.
