WebConstant Function: If the degree is zero, the polynomial function is a constant function (explained above). Linear Function: The polynomial function with degree one. Such as y = x + 1 or y = x or y = 2x – 5 etc. Taking into consideration, y = x – 6. The domain and the range are R. The graph is always a straight line. WebA function is one-to-one (or injective) if it never assigns two input values to the same output value. Or, said another way, no output value has more than one pre-image. So the above function isn’t one-to-one, because (for example) 4 has more than one pre-image. If we deﬁne g : Z → Z such that g(x) = 2x. Then g is one-to-one. 1 how did shackleton rescue his men
