On a piece of paper graph y>-x+2, then determine which answer matches the graph you drew
nadya68 [22]

Answer: The picture.

<em>Note: I originally said that the picture was reversed, but it actually isn't.</em>

Step-by-step explanation:

Start by making a graph and labeling the axis. The function is linear and has a slope of 1/1, since there is no numerical value in front of the -x. It is also negative, which is the reason the graph is reversed. Then you need to go up 2 on the y axis, since it is -x+2. Your point will be at (0,2)

After you have graphed your first point, graph a second point to help you draw the line. To do this move down on point and to the right one point or (1,1). <em>Keep in mind that if the graph was positive you would move up and to the right.</em>

Now on to drawing the line. Draw the line dashed since y is greater than, but not equal to -x+2. After you have dashed the line, shade above the line to show that it is greater than.

A certain isotope decays so that the amount A remaining after t years is given by:
pashok25 [27]

f(h(x))= 2x -21

Step-by-step explanation:

f(x)= x^3 - 6

h(x)=\sqrt[3]{2x-15}

WE need to find f(h(x)), use composition of functions

Plug in h(x)

f(h(x))=f(\sqrt[3]{2x-15})

Now we plug in f(x) in f(x)

f(h(x))=f(\sqrt[3]{2x-15})=(\sqrt[3]{2x-15})^3 - 6

cube and cube root will get cancelled

f(h(x))= 2x-15 -6= 2 x-21
