Just plug in 3 for x
y = -( 2^3 )
y = -( 8 )
y = -8
The x coordinate of the vertex will be the average of the two zeros, here -3 and 5, so x=(-3+5)/2 = 1, f(1)=(1+3)(1-5) = -16.
Answer: (1, -16)
Let's do it some other ways. How about completing the square to turn f in to vertex form?
f(x) = (x+3)(x-5) = x² - 2x - 15 = (x² - 2x + 1) - 1 - 15 = (x-1)² - 16
and now we can read off (1, -16) as the vertex.
The other method is the vertex is x= - b/2a = - (-2)/2(1) = 1.
Three methods, same answer. Good.
False
Cause if you work still like double shift you still gonna get the same amount of money you gonna get
Answer:
this is a simultanious equation and u need one more equation to do it
Step-by-step explanation:
there are many answers if u dont have the second equation.
You can just substitute a number in x then find y
eg.
x= 12/7 , y =0.5
Standard Form: ax² + bx + c = y
Basically, you put all the numbers from greatest to least with exponents then variables.
We have the numbers:
9
-x²
2x^5
-7x
Put these numbers from least to greatest from the exponents.
2x^5 - x² - 7x + 9
The degree of the polynomial is the number with the greatest exponent. In this case, the highest exponent is 5.
The degree of the polynomial is 5.
Best of Luck!
