If f(x) = x2 - 25 and g(x) = x -5, what is the don all real values of x all real values of x except x = 5 all real values of x except x = -5 all real values of x except x = 5 and x = -5

It has a slope of 1 nd a y intercept of -2

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
