For the parent function y= square root x , what effect does a value of b = -2 have on the graph?

A. Horizontal compression by a factor of 1/2 and a reflection across the y -axis
B. Horizontal compression by a factor of 1/2 and a reflection across the x -axis
C. Horizontal compression by a factor of -1/2 and a reflection across the y -axis
D. Horizontal compression by a factor of =1/2 and a reflection across the x -axis

@jim_thompson5910  really need your help with this one

?

jim_thompson5910 · Answer

the value of b is negative, so that means you have a reflection across the y axis

anonymous · Answer

so my answer would be C then correct?

jim_thompson5910 · Answer

close, the compression/expansion factors are always positive

anonymous · Answer

A!!! haha
