28. the cost c per person to participate in a guided mountain biking tour depends on the number of people n participating in the tour. this relationship can be described by the function c = -3n + 60, where 0 < n < 12. what is the rate of change described by this function? a 20 people/tour c $20 per person b -3 people/tour d -$3 per person

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
