The following graphs are transformations of the parent function \(f(x)=ab^{x-h}+k\).
True or False
1) \(f(x)=ab^{x-h}+2\). Is a vertical shift down two units.
2) \(f(x)=ab^{x-4}+k\). Is a horizontal shift right 4 units.
3) \(f(x)=ab^{x+3}+k\). Is a vertical shift up 3 units.
4) \(f(x)=ab^{x-h}-6\). Is a vertical shift down 6 units.
