Answer:

f(2) = 9.

Step-by-step explanation:

Given : f(x) = 2x² – 3x + 7.

To find : What is the value of the function when x = 2.

Solution : We have given that f(x) = 2x² – 3x + 7.

For, x = 2

f(2) = 2(2)² – 3(2) + 7.

f(2) = 2 *4 -6 +7

f(2) = 8 - 6 +7.

f(2) = 2 +7

f(2) = 9.

Therefore, f(2) = 9.

Given:

Consider the below figure attached with this question.

To find:

The value of $(f+g)(x)$ .

Solution:

The given functions are:

$f(x)=|x|+9$

$g(x)=-6$

Now,

$(f+g)(x)=f(x)+g(x)$

$(f+g)(x)=|x|+9+(-6)$

$(f+g)(x)=|x|+9-6$

$(f+g)(x)=|x|+3$

We know that,

$|x|\geq 0$

Adding 3 on both sides, we get

$|x|+3\geq 0+3$

$(f+g)(x)\geq 3$

So, $(f+g)(x)\geq 3$ for all values of x.

Hence, the correct option is A.

Given:
Pool swimming Ocean swimming Total
Age 30 and younger 228 54 282
Over 30 years old 142 185 327
total 370 239 609

Frequencies:
 Pool swimming Ocean swimming Total
Age 30 and younger 228/609 = 0.37 54/609 = 0.09 282/609 = 0.46
Over 30 years old 142/609 = 0.23 185/609 = 0.30 327/609 = 0.54
total 370/609 = 0.61 239/609 = 0.39 609/609 = 1.00

The relative frequency (rounded to the nearest hundredth) of a person over 30 years old who prefers to swim in the ocean is 0.30
