f(X_i) = C_0 + X_1 C_1 + X_2 C_2 + ... + X_11 C_11 True or False: f(X_i) is a linear polynomial function? How many distinct variables are there in f(x_i)? What is the value of the y-intercept in f(X_i), if it can be defined; if it cannot be defined, then type in \"DNE\"
Solution
f(xi) = co + x1 c1 + x2c2 +.....+ x11c11
1) f(xi) is a linear polynomial its true as the highest degree of teh terms is 1
2) distinct variables are x1,x2,...x11
3) to find y intercept we plug x = 0
hence in this case y intercept = co
