Consumer credit of a certain country can be modeled by the function
c(x)=0.21x^4-5.94x^3+50.51x^2-18.53x+1129.13. Find (dc)/(dx)?

Question

≈ nohglf · Answer

c(x)=0.21x^4-5.94x^3+50.51x^2-18.53x+1129.13

dc/dx = 4 * (0.21x^3) - 3 * (5.94x^2) + 2 * (50.51x) - 18.53

= 0.84x^3 - 17.82x^2 + 101.02x - 18.53

answer: dc/dx  = 0.84x^3 - 17.82x^2 + 101.02x - 18.53
