Answer:
Step-by-step explanation:
Assuming that the first exponent in the formula for the curve should be 3, not 2...
The derivative is
The slope of the tangent line at the point (-1, 2) is the value of the derivative at x = -1.
The slope of the normal line is the opposite reciprocal of the slope of the tangent line.
Using the Point-Slope form of a linear equation, the normal line is
Answer: b
Step-by-step explanation:
It would have a variable, and/or coefficients and sometimes constants
You have one of the answers correct. The fraction 4/8 is equal to 1/2
Other answers are: 5/10, 10/20, and 6/12
If you reduced each of those fractions, you'd get to 1/2.
You can use a calculator to find that
4/8 = 0.5
1/2 = 0.5
5/10 = 0.5
10/20 = 0.5
6/12 = 0.5
All fractions mentioned lead to the same decimal value, so this confirms all of the fractions are equivalent to one another.
The answer is X.
In order for it to be a function, there should be only one y-value for every x-value. Graph x is the only one that obeys this rule, therefore it is the answer
