Answer: The correct option is 1.
Explanation:
The given piecewise function is,

It means if x<0, then

If
, then

Since the f(x) is defined for x<0 and
, therefore the function f(x) is not defined for
.
From the graph 2, 3 and 4 we can easily noticed that for each value of x there exist a unique value of y, therefore the function is defined for all values of x, which is not true according to the given piecewise function.
Only in figure the value of y not exist when x lies between 0 to 2, including 0. It means the function is not defined for
, hence the first option is correct.
First, since you are using the order of operations (PEMDAS), you would start in the parenthesis.
<span>-34 + (110 ÷ 25)
-34 + 4.4
Now, you just add the two numbers.
</span>-34 + 4.4 = -29.6
-34 + (110 ÷ 25) = -29.6
I hope this helps!
Answer:
x=-1,-3,2i and -2i
Step-by-step explanation:
By plugging in x=-1, f(x)=0 and x=-3,f(x)=0
That means x+1 and x+3 are roots of the fourth degree polynomial.
(x+1)(x+3)=x²+4x+3
Divide the polynomial by x²+4x+3 and that gives x²+4.
We now find the zeros of the factors
(x²+4x+3)(x²+4)=0
x=-1,-3,2i and -2i
