How is this even a real question? None of this depends on stats or factual evidence, it is all based on if they feel good, they want to build a model train, or maybe if they have to eat dinner in between. I honestly don't know how you are going to get an answer to this question :/ Tell whoever asks you the question that they need to reword it

Took Gage 1 of a gallon of paint to create a mural of his favorite team the Grizzlies. He was asked to replicate his mural for 8
Charra [1.4K]

Answer: He will need 8 gallons of paint for the other murals.

Step-by-step explanation:

Given: 1 gallon of paint was required to create 1 mural.

Since replicates have the same dimensions, i.e same total surface area.

So, if 8 replication need to be made, the quantity of the paint required for this will be

8  x (Quantity required for 1 mural)

= 8 x 1

= 8 gallons

Hence, he will need 8 gallons of paint for the other murals.

What is the effect on the graph of the function f(x) = x2 when f(x) is changed to f(x − 6)?
suter [353]

Answer:

Horizontal translation in the +x direction.

Step-by-step explanation:

A function of the form f(x) experiments an horizontal translation when the following substitution is applied:

x \to x + a, where a \in \mathbb{R}

If a > 0, the function is translated in the -x direction, whereas a < 0 is the case for the function being translated in the +x direction.

The effect on the graph can be defined by a composition between two function:

f(x) = x^{2}, g (x) = x-6

f\,\circ\,g\,(x) = (x-6)^{2}

The resulting expression represents a horizontal translation in the +x direction.

Finally, we plot f(x) (red) and f\,\circ g\,(x) (blue) by a graphing tool and proved the certainty of this theory.
