X^2 + 3x - 4 = 6
x^2 + 3x - 10 = 0 (Now reverse FOIL)
(x + 5)(x - 2)(Now x will equal the opposites of your numbers)
x = -5
x = 2

Express your answer as a polynomial in standard form
Bingel [31]

Answer:

f(g(x)) = 4x² + 16x + 13

Step-by-step explanation:

Given the composition of functions f(g(x)), for which f(x) = 4x + 5, and g(x) = x² + 4x + 2.

<h3><u>Definitions:</u></h3>
  • The <u>polynomial in standard form</u> has terms that are arranged by <em>descending</em> order of degree.
  • In the <u>composition of function</u><em> f  </em>with function <em>g</em><em>, </em>which is alternatively expressed as <em>f  </em>° <em>g,</em> is defined as (<em>f </em> ° <em>g</em>)(x) = f(g(x)).

In evaluating composition of functions, the first step is to evaluate the inner function, g(x). Then, we must use the derived value from g(x) as an input into f(x).

<h3><u>Solution:</u></h3>

Since we are not provided with any input values to evaluate the given composition of functions, we can express the given functions as follows:

f(x) = 4x + 5

g(x) = x² + 4x + 2

f(g(x)) = 4(x² + 4x + 2)  + 5

Next, distribute 4 into the parenthesis:

f(g(x)) = 4x² + 16x + 8  + 5

Combine constants:

f(g(x)) = 4x² + 16x + 13

Therefore, f(g(x)) as a polynomial in <em>x</em> that is written in standard form is: 4x² + 16x + 13.

The green valley zoo has a new colony of 17 egyptian fruit bats. it costs the zoo 0.86 per day to feed each bat a variety of sof
N76 [4]

It costs the zoo 0.86 per day to feed each bat a variety of soft fruits, therefore the cost of 17 egyptian fruit bats would be $14.62

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

A quadratic equation is in the form:

y = ax² + bx + c

it costs the zoo 0.86 per day to feed each bat a variety of soft fruits. Hence:

Cost of 17 egyptian fruit bats = $0.86 per day * 17 = $14.62

It costs the zoo 0.86 per day to feed each bat a variety of soft fruits, therefore the cost of 17 egyptian fruit bats would be $14.62

PLEASE ANSWER ASAP WILL MARK BRAINLIEST SHOW WORK
goldenfox [79]

Answer: y=23

Step-by-step explanation: You find the slope by doing rise over run. You go up 6 units and right two units to get from your first point to your second point. (This means your slope is 6/2 which is 3 btw). So with this problem specifically, you can see that the y values increase by 6 each time so all you do is add 6 again since it is a linear (straight line) function

10 4 1 add these numbers and you got 15 now you divided by three because there are three numbers so it's 5 because 15 div by 3 is 5
