Answer:
5x^3+6x^2+x-7
Step-by-step explanation:
f(x) = 4x^3 - 2x and g(x) = x^3 + 6x^2 + 3x - 7,
f(x)
+ g(x)= 4x^3 - 2x+ x^3 + 6x^2 + 3x - 7
4x^3 + x^3 + 6x^2 + 3x- 2x - 7
Combine like terms
5x^3+6x^2+x-7
Answer:
Option B.
Step-by-step explanation:
It is given that a delivery truck driver charges a fixed base price of $6 for 2 miles.
After 2 miles, he charges an additional $2 for every mile and after 6 miles, he charges an additional $4 for every mile.
We need to describe the cost of the delivery truck between 1 mile and 2 miles.
In the given graph x-axis represents the distance in miles and y-axis represents the cost in dollars.
From the given graph it is clear that the value of function is constant between x=1 and x=2.
It means the cost of the delivery truck between 1 mile and 2 miles is constant.
Therefore, the correct option is B.
A square root is doing the opposite of squaring. Squaring is multiplying a number by itself. Square rooting is trying to figure out what number squares into the number you have currently.
For your Example 1, the square root of 9 is 3.
3 x 3 = 9.
Some better examples are:
4 x 4 = 16.
4 is the square root of 16, and 16 is the square of 4.
