Well u have a basic equation y=a • b^x a is the initial amount b is the growth factor and x is the exponent
the first step is to make a chart with ur two points for example (0,4) and (2,16) so ur chart will be x. | y. 0. | 4 2. | 16 next you find the difference between the x side so 0 to 2 is +2 then find the difference between the y side so 4 to 16 is +12 then put it into a fraction with y over x or y/x so 12/2 then simplified 6/1 or just 6.
6 is the growth factor and to find a u have to go on the y column and find the first number so a is 4 x is still x because it's 0 but if it was 2 then it would be x-2 so it can cancel so the answer would be y=4 • 6^x
<span>In mathematics, the </span>absolute value<span> <span>or modulus. | x. | of a real number x is the
non-negative </span></span>value<span> of x
without regard to its sign. So both shawn and brielle are correct since
both function will have the same answer, because it will just cancel out the
sign.</span>
