Answer: 0
Reason: the y axis number is 8 on both coordinates, meaning the line is infinite from left to right like so:
<---------------------------------->
Important: Don't confuse this with undefined slope! that would be a vertical line, not a horizontal one.
Answer:
y = - 4, y = 0
Step-by-step explanation:
Given
y² + 4y = 0 ← factor out y from each term on the left side
y(y + 4) = 0 ← in factored form
Equate each factor to zero and solve for y
y = 0
y + 4 = 0 ⇒ y = - 4
Answer: 12
EXPLANATION
An exponential function is in the form y = f(x) = a
· b^x
Given,
When x = 0, y = 3
When x = 1, y = 6
Therefore,
Since y = a · b^x
When x = 0, y = 3
3 = a(b^0)
Any value raised to the power of 0 = 1
Therefore a = 3
So the exponential function we are considering is rewritten
as y = f(x) = 3 · b^x
Since y = 3 · b^x
When x = 1, y = 6
6 = 3 · b^1
6 = 3b
3b = 6
Divide both sides of the equation by 3
3b/3 = 6/3
b = 2
So the exponential function we are considering is rewritten
as y = f(x) = 3 · 2^x
When x =2, y = r
To find the value of r
y = f(x) = 3 · 2^x
r = 3 · 2^2
r = 3 · 4
r = 12
Therefore, the value of r that will make the table a
representation of an exponential function is 12
The best method here is to plug in so plug in -1 (-1)+5+3(-1)=1 so the answer is A
