Q1

Is the expression 8x-3 3 - 5x10 a polynomial in x? If this expression is not a polynomial in x, what rules it out? O This is not a polynomial because x appears under a radical. O This is a polynomial. O This is not a polynomial because x has a negative coefficient. O This is not a polynomial because x appears in the exponent. O This is not a polynomial because x appears in the denominator.Is the expression below a polynomial in P? O This is not a polynomial because P appears in the denominator. O This is not a polynomial because P appears in the exponent. O This is a polynomial. O This is not a polynomial because P appears under a radical. O This is not a polynomial because P has a negative coefcient. The function g (x) = 1 + 1 -x + 16 x is used to approximate the values of f (x) = Evaluate f and gat x = 0. - X What does this tell you about the graphs of these two functions? f (0) = i 8 (0) = i They have the same1 This problem refers to the functions f(x) and g (x), where the function g (x) = 1 + Ex + $362 + 156363 is used to approximate the 1 values off(x) = Evaluate f (x) and g (x) at x = 0.1, 0.2, 0.3 and record your answers to three decimal places in a table. Does your table support the claim that g (x) gives a good approximation to f(x) for these values of x ? m E E l m l E E v the claim that g (x) gives a good approximation for f (x) for values of x. No. The table does not support Yes. The table does support
