Solve this system of inequalities graphically 3-y<6, x>1, y<3
Answered by bobpursley
rearrange the equations to ...

y>-3 and
x>1 and
y<3

This means that y is between -3 and 3, x>1

Does that help?

If f (x) - 4x - 3, find the following f (-1)
Answered by Damon
Sorry, I can not graph this for you.
However
3 - y < 6
Multiply both sides by -1, when you multiply inequality by negative quantity, change direction of arrow
-3 + y > -6
or
y > -3
So everything above the horizontal line y = -3 is in so far.
x>1 so everything above -3 and right of x = 1 is in so far
y <3 so everything between y = -3 and y = +3 and right of vertical line x=1 is in

Mary, use - 1 for x

Since you did not type an equal sign I assume you mean
If f (x) = 4x - 3, find the following f (-1)

f(-1) = 4 *(-1) - 3

= -4 -3

= -7
