Bradley received his federal stimulus check of $1,600. He deposited it into a foreign account. His fiduciary says he will have $2,000 this time next month. If the same
exponential growth rate continues each month, which of the functions below would
best model this growth? (Let X be the number of months he plans to keep his money
in the account.)

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
