Let f(x)=8xf(x)=8x. the graph of f(x)f(x) is transformed into the graph of g(x)g(x) by a vertical stretch of 4 and a translation of 7 units down. what is an equation for g(x)g(x)?

Step-by-step explanation:

A vertical stretch transformation means that we have to multiply the stretch factor to the x-variable, that way y-values will be stretched.

A translation downwards is accomplish by subtracting units to f(x), that is, to y-variable.

So, according to the rules, the equation would be:

Therefore, the final function transformed is

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
