What statement correctly describes the key features of the graph of f(x) = 4(one half)x + 1 − 3? . y-intercept of (0, −5), starts up on the left, gets closer to y = −3 on the right. y-intercept of (0, −5), starts down on the left, gets closer to y = −3 on the right. y-intercept of (0, 5), starts up on the left, gets closer to y = −3 on the right. y-intercept of (0, 5), starts down on the left, gets closer to y = −3 on the right. @ganeshie8

For what values of b will f(x)= logbx be a decreasing function? (16 )

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?

Which one is the correct answer, and why?
