which of the following about the function f(x) = 2x, 0<x<1 1, x=1 -x+3, 1<x<2 is not true? a. f(1) does not exist b. limx->0+ f(x) exists c. limx->2- f(x) exists d. limx->1 f(x) exists e. limx->1 f(x) ≠ f(1)

"a ball is thrown upwards with initial velocity 20 m/s. After reaching maximum height, on the way down it strikes a bird which is 10 m above the ground. What is the velocity of the ball when it hits the bird?" I know acceleration would be -9.8 m/s^2 (to a...

"the values f(x) of a function f can be made arbitrarily large by taking x sufficiently close to 2 but not equal to 2. Which of the following statements must be true? a. f(2) does not exist. b. f is continuous at x=2. c. limx→2f(x)=∞ d. limx→∞f(x)=2 would...

"find the point(s) on the parabola f(x) = x^2 - 1 whose tangent lines pass through the point (3,7)." I got (4,15) and (2,3). Would that be correct? I think my x is right but I'm not sure if the y is right because I just plugged it back into the equation x...

wouldn't it be a coefficient? Because a coefficient is the number you put before the x to denote the quantity

ok! thank you so much

Ohhh ok. Thank you so much! :D

ok. thanks :D

you would divide 28 by 4. 28 divided by 4 is equal to 7. Dividing a negative number (-28) by a positive (4) yields a negative number so that 7 would become a -7.

Wouldn't the average just be 7.8?
