A function f(x) is said to have a jump discontinuity at x=a if: 1. limx→a− f(x) exists.

2. limx→a+ f(x) exists.

3. The left and right limits are not equal.

Let f(x)= {3x-3 if x <10

{4/x+4 if x ≥ 10

Show that f(x) has a jump discontinuity at x=10 by calculating the limits from the left and right at x=10.

lim f(x)=

x->10^-

lim f(x)=

x->10^+

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
