Answer: Choice D)
F(x) > 0 over the inverval (-infinity, -4)
Translation: The y or f(x) values are positive whenever x < -4.
========================================================
Further Explanation:
Recall that y = f(x), so if we say something like f(x) < 0 then we mean y < 0. Choice A is false because points on the curve to the left of x = -4 have positive y coordinates. Similar reasoning applies to choice B as well.
Choice C is false because while the interval (-infinity, -4) is above the x axis, the portion from x = -4 to x = -3 is below the x axis.
Choice D is true because everything to the left of x = -4 is above the x axis. Pick any point on the blue curve that is to the left of x = -4. This point will be above the horizontal x axis. Keep in mind that the parenthesis notation attached to the -4 means we dont include -4 as part of the interval.

Answer:
62.5 interest on 2500 loan
Step-by-step explanation:
Given that,
amount of loan bank has granted = 2500
number of years = 90 days
90 days = 3 month
3 months = 1/4 year = 0.25 year
interest rate = 10%
= 10 / 100
= 0.1
Formula to use
Principal * interest rate expressed as a decimal * time in years
2500 * 0.1 * 0.25
62.5
Hence, the interest on the loan of 2500 with 10% interest rate for 90 days is 62.5
