If f(x) =4x^2 + 1 and g(x) =x2 -5, find (f+g)(x)

Lilit [14]

The value of $(f+g)(x)$ is $5 x^{2}-4$

Explanation:

Given that the functions $f(x)=4 x^{2}+1$ and $g(x)=x^{2}-5$

We need to determine the value of $(f+g)(x)$

The value of $(f+g)(x)$ can be determined by substituting the value of $f(x)$ and $g(x)$ and simplifying the terms.

Thus, let us assign $f(x)=4 x^{2}+1$ in the function $(f+g)(x)$ , we have,

$4 x^{2}+1+g(x)$

Now, let us assign $g(x)=x^{2}-5$ in the function $(f+g)(x)$ , we get,

$4 x^{2}+1+x^{2}-5$

Grouping the like terms, we have,

$4 x^{2}+x^{2}+1-5$

Adding the like terms, we get,

$5 x^{2}-4$

Hence, the value of $(f+g)(x)$ is $5 x^{2}-4$

Answer: (B) min = -14, max = -3

<u>Step-by-step explanation:</u>

The minimum is the y-value of the vertex of a positive (U-shaped) parabola. In the graph, the vertex is located at (4.5, -14). The y-value of the vertex is -14.

The maximum is the y-value of the vertex of a negative (∩-shaped) parabola. In the graph, the vertex is located at (1.5, -3). The y-value of the vertex is -3.

Pls help or i will get an F<br> one easy question

Ne4ueva [31]

Answer:

p = 5.88/3 –.75

The original be price was $1.21 per lb pound

Step-by-step explanation:

To find the new price per pound, divide 5.88 by 3.

Then subtract .75 from the new be price to find the original price.

5.88/3 = 1.96

1.96 –.75 = 1.21

Determine the value of x. <br>Do,k (x, 9) (-10, -6) A. 5 B. 7 C. 12 D. 15

katen-ka-za [31]

The value of x in D o,k (x,9) -> (-10,-6) is (d) 15

<h3>How to determine the value of x?</h3>

The dilation rule is given as:

D o,k (x,9) -> (-10,-6)

Write out the coordinates

(x,9) -> (-10,-6)

Express as fraction

x/9 = -10/-6

Multiply both sides by 9

x = -9 * 10/-6

Evaluate the product

x = 15

Hence, the value of x in D o,k (x,9) -> (-10,-6) is (d) 15
