Question

What is the effect on the graph of the parent function(x) = x when f(x) is replaced with 8f(x)?A)shifts the line 8 units upB)shifts the line 8 units downQincreases the slope of the line by a factor of 8D)decreases the slope of the line by a factor of 8

Answer 1

When one multiplies the original function f(x) by a positive constant larger than ONE, the effect of such transformation is the increase of the slope of the line by a factor of 8.

The line becomes steeper . So please select the answer labeled C).
