F(x) = x^2. What is g(x)?

Which expression calculates the speed in meters per second of an object that travels a distance of 100 m every 20 seconds

(a) (8%) compute the probability of an even integer among the 100 integers 1! , 2! , 3! , until 100! (here n! is n factorial or n*(n-1)*(n-2) *… 1) (b) (16%) compute the probability of an even integer among the 100 integers: 1, 1+2, 1+2+3, 1+2+3+4, …., 1+2+3+… + 99, and 1+2+3+… + 100

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)
