For each exponential function, a) write a new function, and b) sketch the corresponding graph (on the same coordinate plane) bas
ed on the description of the transformation.
1 answer:
A reflection over the y-axis means that "x" will change signs.
A dilation causes the graph to stretch (if the factor is greater than 1) or shrink/compress (if the factor is between 0 and 1). Usually, the instructions will say whether it is a vertical or horizontal stretch (or shrink) so you know which variable is affected. Since it was not specified, I am going to assume that this is both a vertical and a horizontal shrink.

Answer:
Step-by-step explanation:
A correlation coefficient is a number ranging from -1 and 1 that measures the strength and direction of a linear relationship.
- If it is a negative number, the linear relationship is also negative. If it's positive, the relationship is positive.
- The closer it is to -1 or 1, the stronger the relationship.
Since the question only asks for the strongest relationship and does not ask for the direction (positive/negative), we can simply choose the number closest to -1/1. Therefore, the answer is -0.92.
Answer:
peanuts are more expensive by $1.00.
Step-by-step explanation:
∵ The cost of eight pounds of peanuts = $24.00
∴ The cost of one pound of peanuts =
= $3.00 per pound
∵ The cost of six pounds of walnuts half as much =
= $12.00
∴ the cost of one pound of walnuts =
= $2.00 per pound
Difference in the cost per pound = $3.00 - $2.00 = $1.00
Therefore, peanuts are more expensive by $1.00.
