Answer:
Step-by-step explanation:
If these 3 points are collinear, then we can find the slope of the linear function using any 2 of those points. Suppose we use (-4, 3) and (0, 1):
As we move from (-4, 3) to (0, 1), x increases by 4 and y decreases by 2. Hence, the slope of this lilne is m = rise/run = -2/4, or m = -1/2.
Using the slope-intercept formula y = mx + b and replacing y with 1, x with 0 and m with -1/2, we get:
1 = (-1/2)(0) + b, or b = 1. Then the desired equation is y = f(x) = (-1/2)x + 1
Answer:
A
Step-by-step explanation:
The domain does not exist when the denominater of an equation is zero. So in this case if x was -2 and we added 2 the denominator would be zero, and that value does not exist in the domain. Hope this helps!
The possible answers are 15,5 and 10,10
Answer:
It is about 537.2
Step-by-step explanation:
V= π · r^2 · h
V= π · 3^2 · 19
V≈ 537.2
ANSWER:
According to question, our g(x) becomes f(x) - 5.
When x = 1,
f(x) - 5 = 5 - 5 = 0.
When x = 2,
f(x) - 5 = 7 - 5 = 2.
When x = 3,
f(x) - 5 = 11 - 5 = 6.
When x = 4,
f(x) - 5 = 19 - 5 = 14.
So, <u>Correct choice</u> - [D]
