Answer:

The number is -3

Step-by-step explanation:

Write an equation

2x+4=-10

add 4 on both sides

2x=-6

divide 2 on both sides to isolate variable

x=-3

У = 3(х – 4)2 – 8<br> How do you write this in standard form

aniked [119]

Answer:

$y = 3x^2-24x+40$

Step-by-step explanation:

Hi there!

Standard form: $y=ax^2+bx+c$

$y = 3(x-4)^2-8$

Solve $(x-4)^2$

$y = 3(x^2-8x+16)-8$

Multiply 3 by the parentheses

$y = 3x^2-24x+48-8\\y = 3x^2-24x+40$

I hope this helps!

Explain, in writing, what each parameter in the given function has on the graph of its parent function. (4 Points) () = −cos(1/2

Andrew [12]

Answer:

The parameters in the parent function are:

the parameter correspondig to - 3 in the given function is 0 in the parent function.
the parameter corresponding to 1/2 in the given function is 1 in the parent function, and
the parameter corresponding to - 1 in the given function is 1 in the parent function.

Explanation:

The given function is $f(x)=-cos(x/2)-3$ .

The parent function of $f(x)=-cos(x/2-3)\text{ }is\text{ }h(x)=cosx$ . The parameters of the given function are -1 (which is mutlyplying the value of cosine, 1/2 which is multiplying the argument (x), and - 3 which is subtracted.
