4.f(x)= -1 if x ≤ -6 5 if -6 < x ≤ -2 2x + 9 if x > -2 (1 Point)
I also have part of a table filled out
I just don't understand what I am supposed to do for the first 4 columns.
if i was good at this ill help but me im not that good
I just know about the las column never did any like the first two. I could post other I have already done.
would that help you help me
like what r u suppose to do?
plug in numbers for coordinates and graph it.
Example fx=2x+9 if x > -2
Next you would chose a value for x that is greater than -2 which is 0
oh i have no idea but i can ask my bro to help u
so now its 2(0)+9 which gives us 9 if we solve it and that is our y value
giving us the coordinates for a point at (0,9) if we do a few more we get a graph for two of the columns
I just don't now what to do if there is no x value for the equation.
yeahh im confused on the same thin ur talkin bout o dont get it either
This function works just like any other in the other two sections. For -6 < x < -2, the function is just y = 5, so for any x value in that range you'll get 5 as your result. Similarly, for any x < -6, y = 1.
so any number would be -1 for the first two columns
For the first two columns, you'll want to use different x values, but the y value will always be -1. So for example, the first two columns might look like: \[\left[ -6 | -1 \right]\]\[\left[ -7 | -1 \right]\]\[\left[ -8 | -1 \right]\]
and the graph would be a horizontal line on y=-1 right
thanks a lot I relly needed help understanding this and this is the only question that did those with nothing in the lesson that talked about it. Thanks again
No problem, feel free to message me if you have any other questions.
