CHOICE 1 $1250+5.5% of sales
$5000x0.055=$275+1250=$1525
$10,000x0.055=$550=1250=$1800
CHOICE 2 $2600=2% of sales
$5000x0.02=$100+2600=$2700
$10000x0.02=$200+2600=$2800
So even though more is earned through percentage of sales in CHOICE 1, it doesn't make up for the larger monthly salary of CHOICE 2
Given a quadratic function
y = 4x² - 19x - 5
or i will write it as
4x² - 19x - 5 = y
Zero of the function is when y have the value of zero.
So the quadratic equation will be
4x² - 19x - 5 = y
4x² - 19x - 5 = 0
Now make the equation to intercept form by factorization
4x² - 19x - 5 = 0
(4x + 1)(x - 5) = 0 (this is intercept form)
Solution 1
4x + 1 = 0
4x = -1
x = -1/4
Solution 2
x - 5 = 0
x = 5
SUMMARY
-1/4 and 5 are zero function of f(x) = 4x² - 19x - 5
