Answer:
D
Step-by-step explanation:
your function is not very clear but I'm assuming it's 2 multiplied by 7^x
first let y be equal to the function
to find the range interchange x and y and make the subject
at some point you'll have to use logarithm to get rid of the exponent
only log of positive numbers numbers exist hence y must be greater than 0
Hello,
f(x)=x+8
g(x)=x²-6x-7
f(g(x))=f(x²-6x-7)=x²-6x-7+8=x²-6x+1
f(g(2))=2²-6*2+1=4-12+1=-8+1=-7
Answer A
Answer:
Step-by-step explanation:
Looking at the information given, the average or mean lowest prices and standard deviations for the two cities are given. The standard deviation is a measure of variability. It is used to determine how far the values in the data are from the mean. A lower standard deviation means that the values are closer to the mean. A higher standard deviation means that the values are farther from the mean.
Since 0.07 is lower than 0.23, the correct statement that is true about their gas-price data is
Raquel's data are most likely closer to $3.42 than Van's data are to $3.78.
