False, if we take successive discounts 15% off and then 25% off is not same as taking 40% off at a time.

Step-by-step explanation:

Let Cost price = 100/-

After 15% discount on 100 Cost price is = 100 – 15 = 85

Again on RS. 85/- there is a discount of 25%  

After successive discount of 15% off and then 25% off on Cost price = 85 - 21.25 = 63.75

On the other hand

If 40% discount on the Cost price = 100/-

After successive discount of 40% off on Cost price = 100 – 40 = 60

The cost price by taking successive discount of 15% and 25% off is not same as discount of 40%

Therefore this is false.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
