Which function is increasing?
1 answer:
Answer:
, which is the third function listed among the possible answers.
Step-by-step explanation:
Notice that these are all exponential functions, that contain just "x" in the exponent, and one "1' as the accompanying coefficient. So, in order to decide which ones are increasing, we need to study the base of the expression with exponent "x".
If the base is a number smaller than one, the function is decreasing.
If the base is a number larger than one, the exponential function is increasing.
Therefore, the only one that shows a larger than one base is the third one :
which is therefore the only increasing function of the group.

Im not 100% sure, is the equation supposed to be y=-+1?
Dividing a number by the ratio 3:2 means dividing into 3+2 = 5 parts
Let (0, 0) be (x₁, y₁) and (3, 6) be (x₂, y₂)
Find one part of the share for each axes, we do
Then multiplying the one part back into 3: 2, we have
for the x - axis ⇒ (3×0.6) : (2×0.6) = 1.8: 1.2
for the y - axis ⇒ (3×1.2) : (2×1.2) = 3.6: 2.4
The coordinate that divides the segment into 3 parts and 2 parts is (1.8, 3.6)
