What is the domain of the function graphed below?
2 answers:
The domain of the function graphed is . Option (a) is correct.
Further explanation:
Domain is a set of all the possible values of the function. The value at which the function is defined is known as domain.
Range is a set of values that the function takes.
The output values of the function are known as range and the input values on which function is defined is known as the domain of the function.
Explanation:
The function can’t take the values greater than 7 or equal to 7.
The function is defined for the values of x less than 7. Therefore the domain of the function is .
The domain of the function graphed is . Option (a) is correct.
Option (a) is correct as the domain of the graphed function is .
Option (b) is not correct as the domain of the graphed function is .
Option (c) is not correct as the domain of the graphed function is .
Option (d) is not correct as the domain of the graphed function is .

Answer:
4 + (or -) 3i
Step-by-step explanation:
Hi!
Alright, so we're going to move all of the variables and constants to one side. Then, using the quadratic formula, we'll find the answer.
1. Move 12x-5 to the left side of the equation by
a. Subtracting 12x from both sides
b. adding 5 to both sides.
1: x^2+4x+20-12x+5
2. Group the common terms
x^2+4x-12x+20+5 --> x^2-8x+25
3. Look at the problem. We can't factor this.
Explanation for why this isn't factorable (you can skip this)
(1) 25 is positive, so its two factors will both be either positive or negative. We're looking for a negative 8, so let's go with negative.
(2) Factors of 25: 1 & 25, 5 &5
Seeing the problem? Ya, none of the factors of 25 sum to eight. So, instead, we're going to use the quadratic formula.
4. So, the quadratic formula:
Our equation is x^2-8x+25=0
a is the constant in front of the x^2
b is the constant in front of the x
c is the term without any x values
so, a=1, b=-8, and c= 25
Into equation:
=
=
8/2 = 4
sqrt(-36) = 6i
6i/2 = 3i (remember, we still have the two in the denominator)
4 + (or -) 3i
