Answer:
B, and W are correct i think
Step-by-step explanation:
Answer:
Yes. No graph paper.
Step-by-step explanation:
Let's say the 3 points are A, B, C.
If A, B and C lie on one line then 

Hence, they lie on one line.
You don't need to use a graph paper to prove it.
<span>2^x+4 -12=20
</span><span>2^x+4 = 20+12
</span><span>2^x+4 = 32
</span><span>2^x+4 = 2^5
x+4 = 5
x = 1
answer is </span><span>B. x=1</span>
Answer: y=3x-6
Step-by-step explanation:
Answer:

Step-by-step explanation:
Quadratic function-
It is a function that can be represented by an equation of the form
, where
In a quadratic function, the greatest power of the variable is 2.
As in the first option the highest power is 3, so it is not a quadratic function.
Even though the power of x is 2 in the third option, but as it is in the denominator, so the overall power of x becomes -2. Hence it is not a quadratic function.
As the coefficient of
is 0 in case of fourth option, so it is not a quadratic function.
Equation in option 2 satisfies all the conditions of quadratic function, hence it is the quadratic function.
