f(-2) means the x value is -2 and you need to find the y value at that point.
At x = -2 the line crosses the y axis at y = 2
f(-2) = 2
Answer:
The answer depends on what the problem really is.
f(1/2) = 8
or
f(1/2) = 4
See below.
Step-by-step explanation:
This is the problem as it was posted:
y = f(x) = 16x
Let x = 1/2
y = f(1/2) = 16(1/2) = 8
Perhaps the problem is this:

If x is an exponent of 16 and not a factor, then the answer is:

Answer:
B. The p-value should be higher than 0.05
Step-by-step explanation:
p-value is smaller than 0.05 means that there is significant difference in mean bicep curls made with right hand and left hand.
Since 95% confidence interval for the true mean difference is given as (-9.242, 0.2472), and confidence interval includes the value 0, we cannot say that there is significant difference. Therefore p-value is not smaller than 0.05, it is higher than 0.05.
