1) 8 + (x-4 )^2

= 8 + x^2 -8x + 16

= x^2 - 8x + 24

2) - (x+3) + 3(-x -6)

= -x - 3 -3x - 18

= -4x - 21

3) 2(x -y +z) -4(x -y +z)

= (x -y +z) (2 - 4)

= (x -y +z)(-2)

= -2x + 2y -2z

Which function has only one x-intercept at (−6, 0)?
atroni [7]

Answer:

The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)

Step-by-step explanation:

We have a function:

f(x)=(x+6)(x+6)

This function is also equal to f(x)=(x+6)^2

This is the square of the binomial. It has only one zero

f(x)=(x+6)^2 = 0

If we take square root we get:

√(x+6)^2 = 0

x+6 =0

x= -6

The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)....

Which function is a horizontal compression of its parent function f(x)=x^7 by a factor of 4?
nasty-shy [4]
Note that what we want is to compress any point (a, b) in the parent function, to (a, b/4).

(a, b) is a point of the graph of the function f(x)=x^7, thus we can rewrite the point as:
                                     (a, a^7).

This point is compressed to 

                                   \displaystyle{ (a,  \frac{a^7}{4} ).

This means that the function we are looking for is \displaystyle{ t(x)= \frac{x^7}{4}.

Answer: <span>t(x)=1/4x^7

Write an equation of the line that passes through (2, 2) and is parallel to the line y = 7x
zimovet [89]

Answer:

y = 7x - 12

Step-by-step explanation:

Parallel lines have same slope.

y = mx + b

m - > slope   & b -> y-intercept

y = 7x

So, slope = 7 & (2 , 2)

y - y1 = m(x -x1)

y - 2 = 7(x - 2)

y - 2 = 7x - 14

    y = 7x - 14 + 2

   y = 7x - 12
