The following function represents the production cost f(x), in dollars, for x number of units produced by company 1: f(x) = 0.05x2 − 7x + 300 The following table represents the production cost g(x), in dollars, for x number of units produced by company 2: x g(x) 0.6 899.58 0.8 899.52 1 899.50 1.2 899.52 1.4 899.58 Based on the given information, the minimum production cost for company _____ is greater. [Put 1 or 2 in the blank space]

it is 1 because the minimum would be for one so 293.1 so company 1

what do u need help with?
LynFran

for fx=gx we look where the 2 function intersect but there they only want the x values so x=-4 ,2.5
