Answer:

16r^2-2r

Step-by-step explanation:

2(8r^2+r)-4r

(16r^2 +2r)-4r               Distribute the 2

16r^2+(2r-4r)                Regroup like terms

16r^2-2r

Hope this helps!

For x = 4, then it means 3 to the fourth power or 3 times 3 times 3 times 3 times 3.  3^4 = 81 and 8 times that is 648.

y(x) = 8 * 3^x where x = 4:

y(x) = 8 * 3^4 = 8 * 81
y(x) = 648

The Function Rule then being that for every value of x there is one and only one value of y. y is the dependent variable and x is the independent variable.

The parent function f(x) = x2 is translated such that the function g(x) = –x2 + 6x – 5 represents the new function. What is true
kkurt [141]

Answer:

1. Translation 3 units to the right;

2. Reflection across the x-axis;

3. Translation 4 units up.

Step-by-step explanation:

First, rewrite the function g(x) in following way:

g(x)=-x^2+6x-5=-(x^2-6x)-5=-(x^2-6x+9-9)-5=-(x-3)^2+9-5=-(x-3)^2+4.

Apply such transformations:

1. Translate the graph of the parent function f(x) 3 units to the right to get the graph of the function f_1(x)=(x-3)^2.

2. Reflect the graph of the function f_1(x) across the x-axis to get the graph of the function f_2(x)=-(x-3)^2.

3. Translate the graph of the function f_2(x) 4 units up to get the graph of the function g(x)=-(x-3)^2+4.
