Answer:
36
General Formulas and Concepts:
<u>Pre-Algebra</u>
Order of Operations: BPEMDAS
- Brackets
- Parenthesis
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
Step-by-step explanation:
<u>Step 1: Define</u>
y² - 7y + 6
y = -3
<u>Step 2: Evaluate</u>
- Substitute in <em>y</em>: (-3)² - 7(-3) + 6
- Exponent: 9 - 7(-3) + 6
- Multiply: 9 + 21 + 6
- Add: 30 + 6
- Add: 36
I'd say it's x + 1 < 17.
Because the operator should be included as a person as well.
12x3=36 That is the equation
Hey there!
A function is a relation to numbers in which an input value as a specific output value.
a) Is a function. All x values go to specific y values. For domain, look at the x values. You go from 2 to 8. So, 2≤x≤8 (we can assume the line just goes this long since we are not given anymore information) For the range, we have the same thing. It goes from 5 to 8. 5≤y≤8
b) Is not a function. 1 cannot go to two y-values.
c) Is not a function. Does not pass vertical line test.
d) Is a function. Passes the vertical line test. For the domain on this one, it would be infinite, which you could represent as (-∞,∞) It is infinite because the line as two arrows that continue forever. For the range, it would be anything greater than 2. y≥2 or 2≤y
The question stated you only needed to find the domain and range for the functions, so you would just do it for a) and d).
I hope this helps!

Answer:
Arrow from 0 to 4.7 and from 4.7 to 2.4
Step-by-step explanation:
4.7 is also 0+4.7
arrow from 0 to 4.7.
-2.3 from 4.7 is 4.7-2.3=2.4
arrow from 4.7 to 2.4.
