Answer:
x = 3/4 or x = 0.75
Step-by-step explanation:
y=2x²-3x+4
y'=4x-3 = 0
x = 3/4 .... answer
or
x = - b/2a ...y=ax²+bx+c
x = - (-3)/(2*2) = 3/4

Answer:
{324, 0, -6, 54}
Step-by-step explanation:
Given that F(x) = 3x² − 3 x − 6 If the domain of a the function f(x) is { -10, -1, 1, 5 }.
To get the range, we will find f(x) for all the domains
at x = -10
f(-10) = 3(-10)²-3(-10) - 6
f(-10) = 3(100)-3(-10) - 6
f(-10) = 300+30-6
f(-10) = 330-6
f(-10) = 324
at x = -1
f(-1) = 3(-1)²-3(-1) - 6
f(-1) = 3(1)-3(-1) - 6
f(-1) = 3+3-6
f(-1) = 6-6
f(-1) = 0
at x = 1
f(1) = 3(1)²-3(1) - 6
f(1) = 3(1)-3(1) - 6
f(1) = 3-3-6
f(1) = 0-6
f(1) = -6
at x = 5
f(5) = 3(5)²-3(5) - 6
f(5) = 3(25)-3(5) - 6
f(5) = 75-15-6
f(5) = 60-6
f(5) = 54
Hence the range of the relation are {324, 0, -6, 54}
Answer:
Final Profit = £11,000
Step-by-step explanation:
Incoming / Outgoing Profit / Cost Events £22,765
Staff £6,711
Security £3,452
Maintenance £500
Merchandise £967
Final Profit = £22,765 - £6,711 - £3,452 - £500 - £967 = £11,135
Answer:
False
Step-by-step explanation:
We need both points, because one is the y, adn it is what the equation equals to, and the x is the thing that comes after the slope.
Example:
m=2
(3,0)
y=mx+b
0=(2)(3)+b
0=6+b
0-6=b
-6=b
