Which of the following tables of value represent ordered pairs for the function f(x)=2x-1

1 answer:

6 0

Well without seeing the tables it is hard to answer. However, I will offer some help. f(x) is actually y. A function of x=y. So, now you have y=2x-1. Plug the x and y values in from the tables and make sure the equations are true with the given values (equal on both sides). For example, (2,3).. 3=2(2)-1...... 3=3. Hope this helps.

If x2 mx m is a perfect-square trinomial, which equation must be true? x2 mx m = (x – 1)2 x2 mx m = (x 1)2 x2 mx m = (x 2)2 x2 m

An expression has numbers, variables, and mathematical operations. The equation that must be true so that x²+mx+m is a perfect square trinomial is x²+mx+m=(x+2)².

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

A perfect square trinomial is in the form (a+b)²=a²+b²+2ab. If we compare the perfect square trinomial x²+mx+m, we will get that the value of m should be such that it satisfies the equation $m^2+2m$ . Since there is only one value that can satisfy this equation that is 2.
