Because there is a zero in the expression 12.34 * 0 * 74.91 the product is 0.
The transformation of <span>f(x)=15tanx would be achieved by dilating y</span>=tanx graph 15 times. This transformation will cause y'=15 y. This will increase the value of dilation become 15 times of the original
The transformation of g(x)=15tanx would be achieved by shifting y=tanx graph 15 right. This transformation will cause x'=x+15. This will change the value from tan x into tan(x+15)
The answer is (x,y) = (-2, 16)
do you need an explanation as well?
