This is considered an “easy” Q. Answer is 6, but I keep getting 7.
If f(x)=3x-1 and g(x)=4x+2, what is the value of g(f(0)+2)?
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
E) none of the above
Functions – – Ugh!
A function is defined for x and y such that f(x,y) = -2xy + y + x – 4. So, for x=2 and y=3, f(2,3)= -2x2x3+3+2-4 = -12+1 = -11. If x and y are to be chosen such that f(x,y) = f(y,x), then which of the following restrictions must be placed on x and y?
A) x>0 and y>0
B) x<0 and y<0
C) x = y
D) No restrictions are needed
How to solve q19, pg 154, from your study guide. Thanks.
Hi Mike,
Do you accept SAT II questions ?

B )f(x)=x^2+4
C) f(x)=x^3+4
D) f(x)=x^2+x
E) f(x)=x^3+x
The parabola above is the graph of y= -x^2 + k, where k is a constant.
