The left and right bound limits of the function approach positive infinity, so the limit of this function as x approaches 2 is infinity.
Answer:
B and D
Step-by-step explanation:
a is right because there are numbers that exist that are larger than five and smaller than 9
c is right because again, there are numbers that exist that are larger than -3 and smaller than 7.
b cannot be right because there are no numbers that can be larger than 9 that are also smaller than 5
d also cannot be right because there are no numbers that are less than -5 that are also more than -3.
Answer:
6.1÷8 = 0.7625
31.9÷4 =7.975
4.35÷5 = 0.87
Step-by-step explanation:
Answer:
B. -20
Step-by-step explanation:
8/d = -12/30
We can use cross products to solve
8 * 30 = d* -12
240 = -12 d
Divide each side by -12
240/-12 = -12d/-12
-20 = d
Answer:
![f(x)=x^3-7x-6](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E3-7x-6)
Step-by-step explanation:
If x = 3 is a root of a polynomial f(x), then x - 3 is a factor of this polynomial.
If x = -2 is a zero of a polynomial function f(x), then f(-2) = 0 and x - (-2) = x + 2 is a factor of f(x).
If x = -1 is an x-intercept of the function, then y = 0 and x - (-1) = x + 1 is also a factor of the function f(x).
Therefore, the polynomial expression is
![f(x)=(x-3)(x+2)(x+1)](https://tex.z-dn.net/?f=f%28x%29%3D%28x-3%29%28x%2B2%29%28x%2B1%29)
In standard form:
![f(x)=(x-3)(x^2+2x+x+2)=(x-3)(x^2+3x+2)=x^3+3x^2+2x-3x^2-9x-6=x^3-7x-6](https://tex.z-dn.net/?f=f%28x%29%3D%28x-3%29%28x%5E2%2B2x%2Bx%2B2%29%3D%28x-3%29%28x%5E2%2B3x%2B2%29%3Dx%5E3%2B3x%5E2%2B2x-3x%5E2-9x-6%3Dx%5E3-7x-6)
