Answer:
(-∞ , -6] ∪ [6 , +∞)
Step-by-step explanation:
<u>Let D be the domain of f </u>.
D = {x ∈ IR ; where x² - 36 ≥ 0}
x² - 36 ≥ 0
⇔ x² ≥ 36
⇔ x² ≥ 6²
⇔ √(x²) ≥ √(6²)
⇔ |x| ≥ 6
⇔ x ∈ (-∞ , -6] ∪ [6 , +∞)
Answer:
Use desmos.
Step-by-step explanation:
In the image attached, I graphed the linear function on a graphing calculator. B=7 and the slope is 3.
4x - y = 5 --> 4x = y + 5
substitute
4x + 4y = -4
(y + 5) + 4y = -4
5y + 5 = -4
5y = -9
y = -1.8
solve x
4x = y + 5 = -1.8 + 5 = 3.2
x = 3.2/4 = 0.8
Hello from MrBillDoesMath!
Answer:
The first choice, y = x^3 + 5
Discussion:
Let
y = (x-5) ^ (1/3)
To find the inverse, sway x and y and then solve for y:
x = ( y - 5 )^(1/3) => cube both sides
x^3 = y - 5 => add 5 to both sides
x^3 + 5 = y
So the inverse is x^3 + 5, which is the first choice
Thank you,
