The diagram shows a regular octagon joined to an equilateral triangle . Work out the value of x .

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

(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

it would be a on edgenuit y

the diagram below is your final answer
