Let P(x) = 4x^3 - 2x^2 + 7x - 1, and let Q(x) = P(x)^2. What is the y-intercept of Q(x)?


Thanks so much

Q (x)  = ( 4x^3 - 2x^2 + 7x - 1)^2


Every term in Q(x)  will have an x associated with it except the last one which is "1"


And the y intercept of the function will have an associated x value of 0


So......evey term will evaluate to 0  except the last one


So.....the y intercept of Q(x)  =  1



cool cool cool
