Which of the following accurately shows the range of the function defined below?
Answers
Answer: The answer is (b) (2, ∞)
Step-by-step explanation: We are given a function f(x) in the figure and we are to select out of the given options that accurately shows the range of the function defined.
Therefore, the range of the function f(x) will be greater then or equal to 2. So, the range will be [2, ∞).
Thus, the correct option is (b) (2, ∞).
it's b

Answer:
1. r(x) = [q(x)]/[p(x)] is x ≠ 0
2. r(x) = p(x) * q(x) is All real numbers
3. r(x) = [1]/[p(x) + 16q(x)] is x ≠ -2
4. r(x) = [q(x)]/[p(x) + 2] is x ≠ -1
5. r(x) = [1]/[p(x) - q(x)] is x ≠ 1, 2

Answer:
Option 2 and 3 are not written in explicit form.
Step-by-step explanation:
We have four functions we have to find which one of them are not written in explicit form:
Explicit form is the form in which we can finc the value of n.
Option 1 is correct
y=x because
we can calculate y and x by substituting different values.
Option 2 is incorrect because we can not calculate y from the given equation
Option 3 is incorrect because y=0 we can not find anything.
Option 4 is correct because we can find values of y by substituting different values of x in the given equation that is .

we don't know the sign so it could be
4x^2-8x+60 or
4x^2-8x-60
( if it is the first one, go to AAAAAAA
if it is second one go to BBBBBBBBBBB)
to find the zero fo the function, set the fnction to zero
then factor since if you had xy=0, then assume that x and y=0
AAAAAAAAAA
4x^2-8x+60=0
4(x^2-2x+15)=0
4 you get a nonreal root so the missing sign is probably a negative sign
if you were to graph this one, there is no x intercept
BBBBBBBBB
4x^2-8x-60=0
4(x^2-2x-15)=0
4(x-5)(x-3)=0
x-5=0
x=5
x-3=0
x=3
3<5
smallest zero is 3
I would say the smallest zero is 3
Since you didn't gave us what 60 was either positive or negative, I had to write it in both forms.
Which are y=4x^2-8x+60 or y=4x^2-8x-60.
If your equation has it with a positive 60 then the smallest zero is 2.
If your equation has it with a negative 60 then the smallest zero is -3.
If you need any further explanation due to how I got the answer just let me know. (:

Answer:
When evaluating an algebraic expression the first thing you do is that you observe what would be the first operation applied on the expression.
In order to determine that you need to know the basic concept of PEMDAS
Where as
P stands for Parentheses (brackets)
E stands for exponents
M stands for multiplication
D stands for division
A stands for addition
S stands for subtraction
This is the order that needs to be kept in mind while solving the expression

= 4x - 11
x is the input, y is the output.
So if you want to know what input is needed to get an output of 10, set y to 10 and solve for x:
10 = 4x - 11
21 = 4x
x = 21/4
