Given that f(x) = x2 + 1 and g(x) = -3, multiply the functions (gºf)(x).

stich3 [128]

Answer:

$(g\cdot f) = -3x^2-3$

Step-by-step explanation:

$f(x) = x^2 + 1$

$g(x) = -3$

The problem state to multiply the function $f$ and $g$ so the symbol seems to be incorrect.

We actually want to calculate

$g(x) f(x) =gf(x) = (-3) \cdot (x^2+1)= -3x^2-3$

Note

$g\circ f(x)=g(f(x))=g(x^2+1)=-3$

If 2 - 4(y + 1) = 2y + 16, what is the value of y?<br> Show all work, please.

VladimirAG [237]

Answer:

y = -3

Step-by-step explanation:

2 - 4(y + 1) = 2y + 16

2 - 4y - 4 = 2y + 16

2 - 4 = 6y + 16

- 2 = 6y + 16

- 18 = 6y

-3 = y
