Frank is trying to decide between two job offers. The compensation package for job A includes a $450-per-month health insurance
miv72 [106K]
<span>The yearly value of the health insurance from job A is $4380. To find this, take the $450 per month, and subtract Frank's contribution of $85. 450-85=$365 benefit per month. Multiply the monthly benefit by 12 months to get 365*12=4380. The yearly value of the health insurance from job B is $4620. To find this, take the $500 per month and subtract Frank's contribution, 500-115=385. No multiply the monthly benefit by 12 to get 385*12=4620.</span>

The table below shows selected points from a function.
FrozenT [24]

Answer:

<em>True </em>

Step-by-step explanation:

<em>Rate Of Change Of Functions </em>

Given a function y=f(x), the rate of change of f can be computed as the slope of the tangent line in a specific point (by using derivatives), or an approximation by computing the slope of a secant line between two points (a,b) (c,d) that belong to the function. The slope can be calculated with the formula

\displaystyle m=\frac{d-b}{c-a}

If this value is calculated with any pair of points and it always results in the same, then the function is linear. If they are different, the function is non-linear.

Let's take the first two points from the table (1,1)(2,4)

\displaystyle m=\frac{4-1}{2-1}=3

Now, we use the second and the third point (2,4) (3,9)

\displaystyle m=\frac{9-4}{3-2}=5

This difference in values of the slope is enough to state the function is non-linear

Answer: True
