the graph shown below expresses a redical function that can be written in the form f(x)= a(x+k)^1/n + c. what does the graph tel
Oliga [24]

The value of n given the form of the function is (b) positive odd number

<h3>How to interpret the graph?</h3>

The form of the graph is given as:

f(x) = a(x + k)^1/n + c

For the given graph, we have the following features:

a > 0 --- a is positive

k > 0 --- k is positive

c < 0 --- c is negative

If n is an even number, the function would be undefined because the even root of a number is undefined

However, the function is defined if n is an odd number,

Hence, the value of n given the form of the function is a positive odd number

All sacks of sugar have the same weight. All sacks of flour also have the same weight, but not necessarily the same as the weigh
maksim [4K]
Sugar: x pounds
flour: 2x + 5 pounds
2x + 3(2x + 5) = 40
2x + 6x + 15 = 40
8x = 25
x = 3.125
-> a sack of flour is 3.125 + 5 = 8.125 pounds

What is (f*g)(x)? f(x)=x^4-9, g(x)=x^3+9
sladkih [1.3K]
(x^4 - 9)(x^3 + 9)
This is a binomial * binomial. Use the FOIL method for multiplying.
First, outer, inner, last.
x^4 * x^3 = x^7
x°^4 * 9 = 9x^4
-9 * x^3 = -9 x^3
-9 * 9 = -81
Putting it back together.
x^7 +9x^4 -9x^3 - 81
