2.5 hopefully this helpsss
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = - 2x² + 4x - 2
To find the y- intercept set x = 0
f(0) = 0 + 0 - 2 = - 2 ← y- intercept
The equation of the axis of symmetry is of the form x = c
where c is the value of the x- coordinate the line goes through.
Given the equation in standard form
with a = - 2, b = 4 then the axis of symmetry is
x = - 
= - 
= 1
Equation of axis of symmetry is x = 1
Answer:
range is 0 to 4 and domain is 0 to 10
Step-by-step explanation:
start with lowest y value and go up to the maximum value of y on any point then for domain do the same thing except left to right
Answer:
3(16 + (─40) + 4) = -60
(─10 + 18) × (─1) = -8
Step-by-step explanation:
3(16 + (─40) + 4)
PEMDAS:
3(16+(-40)+4)
3(-24+4)
3(-20)
-60
(─10 + 18) × (─1)
PEMDAS:
(-10+18) x (-1)
8 x -1
-8
These are your answers
Hope this helps!
Im not sure about this one but it could be 12x+75y+21 and b+3+6c / disclaimer may be wrong. have a good day!
