Answer:
Maximum
Step-by-step explanation:
dy/dx = 4 - 4x³ = 0
x³ = 1
x = 1
y = 4 - 1 = 3
There's only one stationary point: (1,3)
Nature:
d²y/dx² = -12x²
x = 1, so -12
Negative means it's maximum turning point
Blank 1: If y is -5 when x is 2, that means the equation here is y = -2.5x. So, if x is 8, that makes the equation y = -2.5(8), which gives you -20.
Blank 2: If y is 3 when x is 1, the equation will be y = 3x. If x is 2, that will give you y = 3(2), which is 6.
Blank 3: If y is -7 when x is -21, the equation will be x = 3y. If y is 9, that will give you x = 3(9), which is 27.
Blank 4: If y is 5 when x is 4, the equation will be y = 1.25x. If y is 18, that makes the equation 18 = 1.25x, which is 14.4.
