Consider a circle whose size can vary. let
r
represent the radius of the circle (in cm) and let
c
represent the circumference of the circle (in cm). suppose the function
f
determines the circumference of the circle in cm,
c
, given its radius length in cm,
r
.

write a function formula for
f
.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
