Find the minimum or maximum value of the function. What is the H? (Desmos)

beks73 [17]

Answer:

Minimum: (2,4)

Step-by-step explanation:

h(x)=3( $x^{2}$ -4x)+16

=3( $x^{2}$ -4x+4-4)+16 (- For the balance of equation, and attention 1)

=3 $(x-2)^{2}$ -3*4+16

=3 $(x-2)^{2}$ +4

<h3>Attention:</h3>

1. $(a-b)^{2}=a^{2} -2ab+b^{2}$

2. The formula for the vertex form is y = $a(x-h)^{2}+k$ , the vertex is (h,k)

Simplify 3/4(1/2×-12)+4/5

Wittaler [7]

Answer: $\frac{3}{8}x-\frac{41}{5}$ or $\frac{3}{8}x-8\ \frac{1}{5}$

Step-by-step explanation:

Given the following expression:

$\frac{3}{4}(\frac{1}{2}x-12)+\frac{4}{5}$

You can follow these steps in order to simplify it:

1. You need to apply Distributive property:

$=\frac{3}{8}x-9+\frac{4}{5}$

2. And now you must add the like terms. Then:

$=\frac{3}{8}x-\frac{41}{5}$

Therefore you get the following answer:

$\frac{3}{8}x-\frac{41}{5}$ or $\frac{3}{8}x-8\ \frac{1}{5}$
