Answer:

B. 14

Step-by-step explanation:

It's asking for function f + function g. Then it wants you to use 2 as the x value. So you have:

(f+g)(x) = 2x^2 + 3x + x - 2

(f+g)(x) = 2x^2 + 4x -2

Then using 2 as x:

(f+g)(2) = 2(2^2) + 4* 2 -2

(f+g)(2) = 8 + 8 - 2

(f+g)(2) = 14

Hope that helps, and let me know if I did any of that wrong.

8. Charlotte is given the equation 3x - 4y = 12. She needs to create a graph of the equation, but
Zielflug [23.3K]

Answer/Step-by-step explanation:

Note:

<u>Graphing From An Equation: </u>

Equation are frequently written in slope-intercept form { y = mx+b}.

Which "m" represents the slope and "b" represents the y-intercept.

<u>Solutions and Equation:</u>

Solutions to linear equations contain any points located on the graphed line.

Ordered Pair = Solution to an equation if it's values are substituted in the equation which makes it true

Solve:

{x = 0 }       3(0) - 4y = 12

                       -4y = 12                                 (0, -3 )

                       -4y/-4 = 12/-4

                                y = -3

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

{y = 0}                  3x-4(0) =12

                                3x = 12              (4,0)

                                 3x/3 = 12/3

                                        x = 4

for lyla: a. state which formula should be used to solve this problem. b. write the function for lyla. c. determine how much lyl
tresset_1 [31]

The formula is P=Poe^rt and after 20 years the amount will be $14134.41

For Lyla, the formula used to solve the problem is P=Poe^rt

The function is P=3000 e^0.775t

After 20 years lyla amount will be P=3000e^0.775×20=14134.41$

  • The exponential function is a type of mathematical function which are helpful in finding the growth or decay of population, money, price, etc that are growing or decay exponentially.
  • Exponents are used in exponential functions, as the name indicates. But take note that an exponential function does not have a constant as its base and a variable as its exponent (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
  • As the name implies, exponential functions employ exponents. The base and exponent of an exponential function, however, are not a constant and a variable, respectively (if a function has a variable as the base and a constant).

Precal question please help I don’t understand
frez [133]

A) True.  The domain of both is: x ≥ 0

B) True. 1/2 is on the outside so it is vertical.  1/2 is between 0 and 1 so it shrinks.

C) False.  the coefficient is not 2 (it is 1/2)

D) False. 1/2 is not on the inside with "x" so it is not horizontal.

Answer: A, B
