Question

Let h be the function with domain all real numbers such that

h(x)=2 | x |.

On grid paper, draw the portion of the graph of h for x-values such that -10 ≤ x ≤ 10.

What is it asking for????? EASY 10 POINTS.

Answer 1

You only need to supply a graph for values of x between (and including) -10 to +10

Select a number of values for x. Perhaps you might select all integers from -10 to +10. For each x calculate the value for h, which will be 2 times the absolute value of x. Plot each x,y pair on your graph.

It will end up looking like a V with the bottom point of the V at (0,0), the left peak of the V at (-10, 20) and the right peak of the V at (10,20).

Answer 2

it is an absolute value function. so, start at -10. plug in -10 for x. when you put -10 into that bracket, it becomes 10, because an absolute value is the distance a number is from zero (the origin). so then you multiply the 2 times 10 and get twenty (20 is the y coordinate). your coordinate would be (-10, 20). you do the same for -9, and you get 18 as the y value. so the coordinates would be (-9, 18). you do this all the way to 10 that it.

Answer 3

Basically this is an absolute value function. First you have to make sure you know what a domain is: It is all the possible values of x in the function. This problem is giving you a set domain, -10 to 10. So, then, you already are given the values for x. Make a table with two columns, x and y. In x, write your set domain. Then put all this values into the equation and find the y values. Then, take these coordinates, graph them, and connect the dots. Because it is an absolute value equation, it should look like a V.

Hope that helps.
