Step-by-step explanation:
a) Let y = f(x) = 3x - 2x^2
f(-2) = 3(-2) - 2(-2)^2 = p
= -6 - 8
= -14
= p
f(2.5) = 3(2.5) - 2(2.5)^2 = q
= 7.5 - 12.5
= -5
= q
b) graphing
c) From the graph, you should be able to verify the following:
i) f(0.5) = 3(0.5) - 2(0.5)^2 = 1
ii) 0.5 = 3x - 2x^2 or x = 1.3, 0.2
iii) the maximum occurs at
f(0.75) = 1.125
d) the equation for the line of symmetry is x = 0.75
I don’t know if you still need the answer but it would be C) 3204 in.
Answer:
y=-2/3x -6
Step-by-step explanation:
y=-6 so b=-6
rise/run=-2/3
Put that into an equation of y=mx+b and you get y=-2/3x -6
Answer:
97.425
Step-by-step explanation:
C▲RST/C▲XYZ=1/3
S▲RST/S▲XYZ=1/9
The area of ▲RST is 10.825
SO the are of ▲XYZ is 10.825*9=97.425
