What is an one-to-one function? (answer)

One to one If you can draw a horizontal line that crosses the graph in more than one place, then the function is NOT one to one. For example, a parabola is a u-shaped graph. You can cross the graph in two places. Any straight line is a one to one graph.

t is 4 more than the product of 7 and s t = 4 + 7s

(2x+1/3)-(x-5/4)=1/2 It looks like there is a confusion about the parenthesis. Start by distributing the negative sign ("remove" the negative) 2x + 1/3 - x + 5/4 = 1/2 Combine like terms, the x's. x...

-5(b-4) -5b + 20 is the answer Other examples of distributive problems: 2(x+y) 2x + 2y 9(3+2) 27 + 18 -8(x - y) -8x + 8y (notice that the two negative signs...
