this is on the Barron's SAT Math IIC Book page 41.
Which of the following equations can represent the inverse of the attachment? (the line on the attachment is y=f(x)
a) y=-2x+1
b) y=2x+1
c) 1/2x+1
d) y=1/2x-1
e) y=1/2x-(1/2)
I know that inverse means that for example the inverse of function y=2x is y=x/2 but how do you do this problem?
Thanks in advance
from the graph, we see that the line passes through the points (-1,0) and (0,1). from this we can find the slope, and then we can find the equation of the line.
there seems to be a lot of mistakes in this problem set that you are doing. there have been several questions now where none of the responses are correct. i suggest you find another source to practice from
