Step-by-step explanation:
Answer: f(f(f(x)))=8x-7
Step-by-step explanation:
Since we were given f(x) and f(f(x)), We plug that into f(x) again to get f(f(f(x))).
2(4x-3)-1 [distribute]
8x-6-1 [combine like terms]
8x-7
You're equation will look like:
R = 1167 + 1167 + 1167 - 239
To get the answer, simplify
R = 1167 + 1167 + 1167 - 239 = 3262

The first thing we are going to do to find (g°f)(3), is find (g°f)(x). To do that, we are going to evaluate g(x) at f(x):
(g°f)(x)=
Now, we can evaluate (g°f) at 3:
We can conclude that the correct answer is
c. 49
Answer:
∫(x+25x)dx=13x²
Step-by-step explanation:
From Exercise, we want calculate integral for x + 25 x dx.
But this not required a substitution to express the integrand as a rational function. We can calculte integral, and we get
∫(x+25x)dx= ∫x dx+25∫x dx=x²/2+ \frac{25}{2} · x^2=\frac{26}{2}·x^2=13x²
Therefore, we get that is
∫(x+25x)dx=13x².
