1 easy algebra Answer T True or F FalseParallel lines have t

Answer T (True) or F (False).________Parallel lines have the same slope.________(f ocy g)(x) = f(x)g(x)________The graph of y = f(x - 2) is obtained by shifting the graph of f 2 units to the right.________The graph of an even function is symmetric with respect to the y-axis.________All real numbers are complex.________With compound interest, only the principal earns interest.________If xy = 0, then we can conclude that x = 0 or y = 0.________If b^2 - 4ac > 0, then the equation ax^2 + bx + c = 0 has two real solutions.________For all real x, |-x| = x.________If a function has no real zero, then its graph has no x-intercept.________All exponential functions are one-to-one.________The logarithm of a negative number is not defined.________For all positive real numbers x and y, log (xy) = log x + log y________For all positive real numbers x and y, log (x - y) = log x/log y.________Natural logarithms are logarithms with base 10.
