Question

If you vertically stretch the exponential function f(x)= 2^x by the factor of 4, what is the equation of the new function

Answer 1

to vertically strech a function by a factor of c, multiply the whole function by c

so

f(x) vertically streched by a factor of 4 is 4f(x)

so we get

the new function is f(x)=4(2)ˣ
