Yeah i agree with the question
Answer:
f(x) = -4x²+24x -28
Step-by-step explanation:
The given zeros are a sum and a difference. You can use the special factoring of the product of a sum and difference to simplify the product of the factors of the quadratic. Each zero 'p' corresponds to a factor (x -p):
f(x) = a(x -(3 +√2))(x -(3 -√2)) = a((x -3)² -(√2)²) = a((x -3)² -2)
We can find the leading coefficient 'a' from the given point:
f(1) = -8 = a((1 -3)² -2) = 2a
a = -8/2 = -4
Then the function can be written as ...
f(x) = -4((x -3)² -2) = -4(x² -6x +9 -2)
f(x) = -4x²+24x -28

Answer:
1511
Step-by-step explanation:
I know it's not a 3 digit number, but it's impossible to make a 3 digit number in your specifications.
Answer:
Graph 1:
y-intercept = 7
Slope = -1/2 <--- (It's a fraction) (-1 over 2)
Equation: y = -1/2x + 7
________________________________
Graph 2:
y-intercept = 4
Slope = 5/6 <--- (It's a fraction) (5 over 6)
Equation: y = 5/6x + 4
_________________________________
Graph 3:
y-intercept = 9
Slope = -5/7 <--- (It's a fraction) (-5 over 7)
Equation: y = -5/7x + 9
Hope this Helps :)
