For f(x)=2x+1 and g(x)=x^2-7, find (f.g)(x)

hram777 [196]

Option C (in the figure) is correct.

Step-by-step explanation:

We need to find (f.g)(x)

Given that $f(x)=2x+1\\g(x)= x^2-7$

Now finding (f.g)(x)

$(f.g)(x)= f(x).g(x)$

$(f.g)(x)= (2x+1)(x^2-7)\\(f.g)(x)=2x(x^2-7)+1(x^2-7)\\(f.g)(x)=2x^3-14x+x^2-7\\(f.g)(x)=2x^3+x^2-14x-7$

So, $(f.g)(x)=2x^3+x^2-14x-7$

Option C (in the figure) is correct.

Rosa is saving money for a trip. She has already saved 250$ and plans to save $40 per week. This situation can be represented by

Grace [21]

Answer:

After 6 weeks Rosa has saved $490.

Step-by-step explanation:

1. You have the function given in the problem above, where $x$ os the number of weeks:

$f(x)=250+40x$

2. Therefore, to solve this problem you only need to substitute 6 weeks (or $x=6$ ) into the given function, as following:

$f(x)=250+40x\\f(6)=250+40(6)=490$

3. The result is $490.
