The graph of function g is a vertical stretch of the graph of function f by a factor of 3. which equation describes function g? a. g(x)=3f(x) b. g(x)=f(3x) c. g(x)=f(x3) d. g(x)=13f(x)

Question says that the graph of function g is a vertical stretch of the graph of function f by a factor of 3.

Now we have to find about which equation describes function g.

We know that if f(x) is the given function then a*f(x) gives vertical stretch or compress by a factor of a.

when 0<a<1 then it compresses by factor of a.

when a>1 then it stretches vertically by factor of a.

Given that function f is stretched by a factor of a so that means  we use a=3 in formula a*f(x)

Hence final answer will be g(x)=3f(x).

So choice A is correct answer.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
