identify the domain of the expression
Show that the function f: N x N - > N x N, f(x,y) = (x+y, 2x-3y) is one-to-one. (A function f is said to be one -to -one , or injective , if and only if f ( a) = f ( b ) implies that...
Need help, please!!
How would you find the domain for f(x) = 2x - 4x^1/2 + 2 ? I'm not exactly sure what to do/what steps to take. Do you factor out a 2x1/2 from the whole problem and then get 2x1/2 times x2-3x+2...
How do you solve this and express the answer in interval notation? Explain. g(x) = 10/(x + 7)
