Which of the following expressions represents a function? a. {(1,2), (4,-2), (8,3) , (9,-3)} b. y^2=16-x^2 c. 2x^2+y^2=5 d. x=7

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

step-by-step explanation:

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
