Answer:
The function in the fourth option will have an axis of symmetry at x = 3.
Step-by-step explanation:
We have to choose the function from options, the graph of which has an axis of symmetry at x = 3.
The function in the fourth option will have an axis of symmetry at x = 3.
It is f(x) = x2 – 6x – 1 On a coordinate plane, a parabola opens up. It goes through (0, negative 1), has a vertex at (3, negative 10), and goes through (6, 0). (Answer)
So this means W(-3x) = 3x. So it's equal to 3(-3x), which simplifies to be -9x. Whenever you have a function, it looks like f(x). f doesn't have to be the letter, it can be a, b, c, or like in this case, W. It just means the output of what W(x) is if x equals the number in the parentheses, which is -3x in this case.
Answer:
2/10 (4/5)-(5/2)+ (10)=7.66
So much stuff at once...
I'm only going to give you the information needed to do this.
All of these involve the 4 main exponent laws.
1) Multiplying.
When you multiply two 'numbers' that share the same base, you add exponents and keep the base the same. (ex. 4g²(4g⁴) = 4g²⁺⁴ = 4g⁶)
2) Dividing.
When you divide two 'numbers' that share the same base, you subtract exponents and keep the base the same. (ex. 3a⁷ / 3a⁴ = 3a⁷⁻³ = 3a³)
3) To the power of 1.
Anything to the power of 1 is the same. (ex. 5a¹ = 5a)
4) To the power of 0.
Anything to the power of 0 = 1. (ex. 2d⁰ = 2(1) = 2)
This should help.
