Please help If you vertically stretch the exponential function f(x)=2^x by a factor of 5, what is the equation of the new function A.f(x)=5(2^x)B.f(x)=10^xC.f(x)=7^xD.f(x)=2^(5x)
Accepted Solution
A:
A vertical stretch of f(x) by a scale factor of a is g(x)=a f(x)
For [tex]f(x)=2^x[/tex], and a=5 the vertically stretched function is then [tex]g(x)=a f(x)=5*2^x[/tex]
