Question 81836: Graph the function.
f(x)=-2x+7


iff(x)=4x-3 find the following f(-1)

You can put this solution on YOUR website!
f(x)=-2x+7

This is the graph of a straight line whose y intercept is 7 and whose slope is -2. There are several ways to graph it, but it should look like this:
graph%28300%2C300%2C-10%2C10%2C-10%2C10%2C+-2x%2B7+%29+

For your second question:
if f(x)=4x-3 find f(-1). This means that x=-1, so substitute this for x:
f(-1) =4(-1) -3
f(-1)=-7
