Ok so basically there are many solutions here but I chose this one because I felt it was a good choice for this specific topic, 3(x+12) and can also be written as 3x+36. Hope this helped, do note that there can be many solutions and that I just picked one. If you have any questions feel free to ask!

What is the range of the following function
Shtirlitz [24]

The answer: -5 ≤ y ≤ 6

The range is all the possible output or y values of the function.

Our first point is at (1, 6) and our second point is at (-4, -5)

That means our y values are 6 and -5. Let's set up a compound inequality to represent our function.

-5 ≤ y ≤ 6. This means that x is greater than or equal to -5 and less than or equal to 6.

I need help with this function
viva [34]
f(x)=3x^2+1\\
g(x)=2x+2\\\\
y=2x+2\\
2x=y-2\\
x=\dfrac{1}{2}y-1\\
g^{-1}(x)=\dfrac{1}{2}x-1\\\\
(f\cdot g)(x)=f(x)\cdot g(x)\\\\
(f\cdot g^{-1})(2)=(3\cdot2^2+1)(2\cdot2+2)\\
(f\cdot g^{-1})(2)=(12+1)\cdot6\\
(f\cdot g^{-1})(2)=13\cdot6\\
(f\cdot g^{-1})(2)=78
