For an extremely clueless student who is unsure where to start, how would you recommend preparing for the SAT subject test for Maths 2? Thank you for your time!!

If f and g are functions, where f(x) = x^3 -10x^2 +27x – 18 and g(x) = x^3 – x^2 – 6x, which of the following gives a relationship between f and g?

A) g(x) = 3 f(x)

B) g(x) = f(x) – 3

C) g(x) = f(x) + 3

D) g(x) = f(x – 3)

E) g(x) = f(x + 3)

Can you solve w/o graphing?

A) -5 ≤ x ≤ -3

B) -3 ≤ x ≤ -1

C) -1 ≤ x ≤ 1

D) 1 ≤ x ≤ 3

E) 3 ≤ x ≤ 5

Can you solve w/o graphing?

# what is the difference between the maximum value of y=-x^4-2x^3+5 and the minimum value of y = x^4+x^2-4

what is the difference between the maximum value of y=-x^4-2x^3+5 and the minimum value of y = x^4+x^2-4

# A video store rents, on average, 240 videos a day for $2.00 each…

A video store rents, on average, 240 videos a day for $2.00 each. The store determined that for every $0.25 that it increases the rental fee, the number of daily rentals will decrease by 10. This relationship can be represented by

y=(240-10n)(2+0.25n)

where y is the daily income in dollars from video rentals and n is the number of $0.25 increases. Based on this relationship, at what rental fee per video will the store have its highest daily income?

A)$2

B)$4

C)$4.25

D)$7.75

E)$8

# Subject Test Question: The standard equation of a parabola with focus (2, -3) and directrix x=6 is

Subject Test Question:

The standard equation of a parabola with focus (2, -3) and directrix x=6 is

B) x-4 = -8(y+3)^2.

I did not get this answer. Instead I got (y+3)^2 = -8(x-4)

# If f(x)=[2x]-4x with domain 0≤x≤2, then f(x) can also be written as

Subject Test Question:

If f(x)=[2x]-4x with domain 0≤x≤2, then f(x) can also be written as

A) 2x

B) -x

C) -2x

D) x^2 – 4x

# The area bound by the relationship |x|+|y|=2 is

Subject Test Question:

The area bound by the relationship |x|+|y|=2 is

A) 8

B)1

C) 2

D) 4

E) there is no finite area.

How do you find this algebraically?

# |2x-1| = 4x+5 has how many numbers in its solution set?

Subject Test question:

|2x-1| = 4x+5 has how many numbers in its solution set?

A) 0

B) 1

C) 2

D) an infinite number

E) none of above

How do you find the answer algebraically without graphing it?

# A tetrahedron was cut from the corner of a cube, with three of its vertices at the midpoints of three edges of the cube…

The following question comes from the subject test:

A tetrahedron was cut from the corner of a cube, with three of its vertices at the midpoints of three edges of the cube. If tetrahedrons of the same size are cut from the remaining seven corners of the cube, how many faces will the resulting solid have?

Thank you and big hugs!

# If f(x) = e^x and g(x) = sin x, then the value of (f comp g)( sqrt 2) is ?

Hi Mike,

Do you accept SAT II questions ?

If f(x) = e^x and g(x) = sin x, then the value of (f comp g)( sqrt 2) is ?
