Suppose (1,19) is on the graph of y = f (x). Which of the following points lies on the graph of the transformed function y = f(1

o-na [289]

Answer:

(5,19) lies on the graph of the transformed function y = f(1/5x)

Step-by-step explanation:

Suppose (1,19) is on the graph of y = f (x)

the graph of the transformed function y = f(1/5x)

$y=f(\frac{1}{5}x)$

1/5 is multiplied with x in f(x)

1/5 is less than 1 so there will be a horizontal stretch in the graph by the factor of 1/5

To make horizontal stretch we change the point

f(x)=f(bx) then (x,y) --->( x/b,y)

We divide the x coordinate by the fraction 1/5

(1,19) ----> $(\frac{1}{\frac{1}{5}} , 19)= (5,19)$

So (5,19) lies on the graph of the transformed function y = f(1/5x)

Y = x – 6

Radda [10]

Well x has to be -4 because it says x=-4, and then if you plug -4 into the first equation you'll get y=-4-6 so y=-10. I'm assuming there is a typo, but the answer choice would probably be (-4,-8)
