Answer:

f(x)= 1/4(|x+3|)

Step-by-step explanation:

By putting this answer outside of the parenthesis, it will cut down the answer by 1/4. This stretches the parabola horizontally by decreasing the factor y.

Step-by-step explanation:

*Note:

The definition of a derivative is the slope of the tangent line.

Step 1: Define

Identify.

f(-2.4) = -1

f(-1.9) = -8

Step 2: Differentiate

Simply plug in the 2 coordinates into the slope formula to find slope m.

[Derivative] Set up [Slope Formula]: $\displaystyle f'(-2.4) \approx \frac{f(x_2) - f(x_1)}{x_2 - x_1}$
Substitute in coordinates: $\displaystyle f'(-2.4) \approx \frac{-8 - -1}{-1.9 - -2.4}$
Evaluate: $\displaystyle f'(-2.4) \approx -14$

The number of frogs on the pond is Proportional to the number of salamanders placed in the pond. Suppose there are 10 Frog’s for

bonufazy [111]

Answer:

Y=10x

(multiply 10 times the salamanders)

Step-by-step explanation:

a formula that can be used for this circumstance is a linear y=mx+b problem. for 1 salamander there are 10 frogs. so with this we can state that y=10x. whatever you plug into the x for the number of salamanders will give you the answer of how many frogs are in the pond. for example.

Y=10x

Y=10(3)

Y=30

30 frogs.

also because 10 is a nice number you can just multiply the number of salamanders times 10. 3*10=30
