Let f(x)=6(2)x−1+4 .
The graph of f(x) is stretched vertically by a factor of 4 to form the graph of g(x) .
What is the equation of g(x)
?
Enter your answer in the box.
g(x) =
g(x) = 4 * f(x)
= 4 * ( 6(2)x − 1 + 4 )
= 4 * ( 12x + 3 )
= 48x + 12
Thanks, hectictar...... !!!!
I think this could also be :
f(x) = 6(2)x - 1 + 4
4f(x) = g(x)
4 [ 6(2)x - 1 + 4 ] =
24(2)x - 1 + 16 = g(x)
THANK YOU BOTH!!!!
