Step-by-step explanation:
f (x) + n → shifts the function n units upward.
f (x) – n → shifts the function n units downward.
f (x + n) → shifts the function n units to the left.
f (x – n) → shifts the function n units to the right.
–f (x) → reflects the function in the x-axis.
f (–x) → reflects the function in the y-axis.
STEP 1:
shift the graph 8 units to the left
STEP 2
reflect the graph in the y-axis
Ene score of the first test Is 56. Each test score is 2 points higher than the previous test score. So the score of the second test is 56+ 2 = 58.
The score of the third test is 58+ 2= 60.
And so on.
The scores form an arithmetic sequence 56, 58, 60, ......... with common difference 2.
But the values of the given exponential function \(s(n)=28*2^n\), describe a geometric sequence with common ratio 2.
So the exponential function cannot be used to model this problem.
en la primera
es -2x+7=13, suma 13 con 7 para q tengas 20 y el negativo dos x es la otra asi agarras -2=20 ahora dividelo los dos por 2 te sale 0 para el negativo dos y divide 20/2 son X=10
Answer:
Step-by-step explanation:
Dividing the numerator and denominator by 2 gives;
= 
= 
=

Answer:
It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
