Step-by-step explanation:
By Descartes' Rule of Signs, f(x) = -3x³ + 8x² - 7x + 10 changes sign 3 times, so there are 1 or 3 positive roots.
Answer:
Well to start with, a coefficient is a number that is placed before a variable. In this case we have 10x+8, so the coefficient is well 10.
Step-by-step explanation:
Answer: no
Step-by-step explanation:
Negative numbers can't have real number square roots, but negative numbers can have real number cube roots
In order to figure this out, you must solve the equation.
1-6x=7 (given)
-6x=6 (subtract 1 from both sides)
X=-1 (divide both sides by -6)
The answer is no.
Answer:
B. The graph of g(x) is narrower than the graph of f(x)
D.The graph g(x) is 8 units above the graph of f(x)
check the image given below.
- The blue line refers to graph g(x)
- The red line refers to graph f(x)
