1、一道sat2数学 如图

2、几道SAT2的数学题

1. what is the remainder when the polynomial x^4-5x^2-10x-12 is divided by x+2

2. what are the asymptote of f(x)= 6x^2/4-x^2

我知道x=2和x=-2 但是不知道y=-6 是怎么算出来的

3. what is the y-intercept of the line tangent to the circle x^2+y^2=1 at the point (3/5, 4/5)

不太懂题目的意思

4. Given the statement " If ∠ABC is a right angle, then it measures 90 ," an indirect proof of the statement could begin with which of the following assumptions?

A. ∠ABC does not measures 90

B. ∠ABC measures 90

C. ∠ABC is a right angle

D. ∠ABC is an obtuse angle

E. ∠ABC measures 30

不太懂题目的意思

5. by the rational roos test, how many possible rational roots does f(x)=4x^3-x^2+10x-6 have?

麻烦了
