Answer:
Domain: [-7, ∞)
General Formulas and Concepts:
<u>Algebra I</u>
- Domain is the set of x-values that can be inputted into function f(x)
Step-by-step explanation:
<u>Step 1: Define function</u>
g(x) = √(x + 7)
<u>Step 2: Determine</u>
We know that we cannot have a negative under the square root as it will produce imaginary numbers. Therefore, on a real number scale, the square root can be no less than or equal to 0.
We see from the function that in order to get 0 under the square root, x = -7. If we have x = -8, we would get -1 under the square root, thus giving us an imaginary numbers.
Therefore, our domain is x ≥ -7 or [-7, ∞).
Answer:
Lol! I'll help you!! Remember: listen to your teacher andyoull know this!
Step-by-step explanation:
a (4,2)
b(4,4)
c(-1,-4)
The formula of a slope:
We have the points A(-7, a) and B(c, d).
Substitute:
Exception: c ≠ -7.
=
