Question

You are given the exponential function g(x) = 4–x . Which option below gives the formula for a new function h created by shrinking g by a factor of 2 along the y-axis? h(x) = 4–x–1 h(x) = 2(4–x) h(x) = 0.5(4–x) h(x) = 4–x+1

Answer 1

This is the concept of algebra, given that the exponential function g(x)=4-x was shrunk by a factor 2 along the y-axis, the new size will be given by:
2[h(x)=4-x]
h(x)=2(4-x)
Thus, the new expression for the function is given by h(x)=2(4-x)
