Jack needs an exam average of at least 75 to pass his math course. All five exams are weighted equally and are worth 100 points each. He has earned the following scores on exams so far in the course:...
f(x)= -3x-2 x less than 4 3/4x-1 x greater than or equal to 4 I have figured out the domain is (-infinity,infinity). I am really struggling on...
1. Solve 2^x=32 and rewrite this equation in a logarithmic form. 2. Analyze the characteristics exponential and logarithmic functions. Make sure you talk about domain and range. 3. Demonstrate...
Find the domain of the following functions. a.) p(t)=1/t2-4 b.) t(a)=4√a-2
the < is supposed to be less than or equal to just not sure how to do that
a bicycilat travels at a constant speed of 12 miles per hour for a total of 45 minutes. (Use set notation for the domain and range of the function that models this situation.)

I'm very confused on how you would solve these.
An experimenter gets a range of data: 8.8 * 10^-19 plus or minus 0.1 * 10^-19. This is an experiment about charge. Is this range of error acceptable?
find a polynomial function of degree 2 whose x intercept are -1 and 5 and whose range is (-∞,9)
There are 5 participants in a study. All I have are some statistics to find out the individual numbers for the 5 people. The mean is 8, the standard deviation is 4, the mode is 5 and the range is...
f(x)=sin(arctan x) f(x)=ln(cosx) f(x)=e^tanx
what's amplitude and period for domain and range and how do you find the turning point/point of inflection of Sine cos and tan graphs?
1. f (x) = 3x + 2 3. G (x) = x² + 1 7. H (x) = x² - x + 1 9. f (x) = (2x - 5) / 3 13. F (x) = (x - 2) / 2 My math book, in the answer sheet says that "none"...
What is the range of h(x)=arctan(x)? I know the domain is (-infinity, infinity) and I thought this was the range alos, but I keep getting an incorrect on my answer
