What is the vertex and y-intercept of f(x) = -2x^2 + 4x + 6
1 answer:
F(x)= -2x^2+4x+6
We can use -b/2a to find the line of symmetry
a= -2
b= 4
c= 6
and the x value for the line of symmetry gives you the x value for the vertex
-4/(2*-2)
-1=x
Plug this x value back into the function to find the y value for the vertex
f(x)= -2(-1)^2+(4*-1)+6
f(x)= -2+(-4)+6
f(x)= 0
the c value is the y intercept
Vertex: (-1,0)
Y intercept: 6

Step-by-step explanation:
Answer:
a^2+b^2=c^2 look below
Step-by-step explanation:
Count the squares so
3^2+4^2=5^2
3*3=9
4*4=16
5*5=25
9+16=25 and it does check out
this should help if u need more explanation ill be more then happy to explain to you
Answer:
47
Step-by-step explanation:
$460 + $90 = $550
4 x $20 = $80
$550 - $80 = $470
$470/10 = 47
they have to wash 47 cars
Range is the difference between the largest and the smallest numbers in a given contest
Hence the range
= 46 - 36
