Identify the parent function that can be used to graph the function f(x)=-6[1/2x+3]+2/3

step-by-step explanation:

the linear relationship that represents a variation in direct proportion is the linear function that varies according to the numbers of its domain, for example the cost of producing x number of items can be represented in direct proportion by f (x) = mx + b, where m is the constant of proportionality, x the number of articles produced and b the fixed cost

the answer is d.x= 90°

y= 50°

arc lm= 100°
