Answer:

a. f(-2) = -6

b. f(0) = 6

c. f(2) = 10

Step-by-step explanation:

The function is given as:

f(x) = 5x + 4                                      if x < 0

f(x) = 2x + 6                                      if x ≥ 0

(a) f(-2)

x < 0:

=> f(-2) = 5(-2) + 4

f(-2) = -10 + 4

f(-2) = -6

(b) f(0)

x ≥ 0:

=> f(0) = 2(0) + 6

f(0) = 6

(c) f(2)

x ≥ 0:

=> f(2) = 2(2) + 6

f(2) = 4 + 6

f(2) = 10

ioda

Answer:

D. 14 times

Step-by-step explanation:

The population of New York City is about 8.18 × 10^6. This is an estimation. The population of Las Vegas is about 5.84 × 10^5. This is also an estimation. We want to determine the number of times that population of new York is more than that of las Vegas. It's like saying how many las Vegas are the in New york.

This is done by dividing the population of new York by the population of las Vegas. It becomes

8.18 × 10^6 / 5.84 × 10^5

= 14.00684931507

Approximately 14 times

Solve the following quadratic function<br> by utilizing the square root method.<br> y = 16 – x2
Hunter-Best [27]
Step 1) y=16-x2. Swap the sides so that all terms of the variables are on the left side. Step 2) 16-x_{2}=y. Subtract 16 from both sides. Step 3) -x_{2}=y-16 Divide the two sides by -1. Step 4). \frac{-x_{2}}{-1}=\frac{y-16}{-1} Dividing by -1 undoes the multiplication by -1. Step 5). x_{2}=\frac{y-16}{-1} Step 6) dived y-16 by -1 And the final answer = x_{2}=16-y
