Answer:
0 ≤ x ≤ 10
Step-by-step explanation:
The function representing the spread of virus is:
Where x represents the number of hours after 1:00 pm
So, at 1:00 pm "x" will be equal to 0. So the domain will start from x = 0
According to the given statement, the virus spreads from 1:00 pm to 11:00 pm. So, the number of hours starting from 1:00 pm and ending on 11:00 pm will be the Domain. 11:00 pm means 10 hours after 1:00 pm i.e. x = 10
So, the domains starts at x = 0 and ends at x = 10. Therefore, the correct answer is 0 ≤ x ≤ 10
Answer:
2y + 3x + 7 = 0
Step-by-step explanation:
line equation = y - y1 = m (x - x1)
y - (-5) = -3/2 * (x - 1)
y + 5 = -3/2 (x - 1)
2y + 10 = -3x + 3
2y + 3x + 7 = 0
Axis of symmetry = x = -b/2a
where y = ax² + bx + c
f(x) = x² + 6x - 1 ⇒ a = 1 ; b = 6 ; c = -1
x = -(6)/2(1) = -6/2 = -3
g(x) = -x² + 2 ⇒ a = -1 ; b = 0 ; c = 2
x = -0/2(-1) = 0/-2 = 0
h(x) = 2x² - 4x + 3 ⇒ a = 2 ; b = -4 ; c = 3
x = -(-4)/2(2) = 4/4 = 1
least : f(x) = x² + 6x - 1 ; axis of symmetry is -3
middle : g(x) = -x² + 2 ; axis of symmetry is 0
greatest : h(x) = 2x² - 4x + 3 ; axis of symmetry is 1
Answer:
I don't think any are a correct graph of the function. But here are the ordered pairs. (1,0),(0,-2),(-1,-4)
Step-by-step explanation:
Take three values for x and plug them in for your y's. For instance x values of 1,0,-1. Plug each in to find the y value. 2(1) - 2 =y so (1,0)
