Answer:
When we have a function f(x), the values of x at which the function is not differentiable are:
1) values at which the function is not "soft". So if we have a really abrupt change in the curvature of the function, we can not differentiate in that value of x, because in those abrupt changes there are a lot of tangent lines to them.
One example of this is the peak we can see at x = -4
Then we can not differentiate the function at x = -4
2) When we have a discontinuity.
If we have a discontinuity at x = x0, then we will have two possible tangents at x = x0, this means taht we can not differentiate at x = x0, and remember that a discontinuity at x = x0 means that:
f(x0₊) ≠ f(x0₋)
where x0₊ is a value that approaches x0 from above, and x0₋ is a value that approaches x0 from below.
With this in mind, we can see in the graph a discontinuity at x = 0, so we can not differentiate the function at x = 0.
There r 2 ways to do this type of problem....
(1) 30% of 70...turn percent to decimal...." of " means multiply
0.30(70) = 21.....so 30% of 70 is 21
or
(2) use the percent formula.....is/of = %/100
30% of 70 is what ...
is = x
of = 70
% = 30
is/of = %/100
sub
x / 70 = 30 / 100
cross multiply because this is a proportion
(100)(x) = (30)(70)
100x = 2100
x= 2100 / 100
x = 21
** by the way, this percent formula works on many percent problems...u just have to make sure u sub the right numbers in the right places.
either way u choose to do it, u should arrive at the same answer
Answer:
A point whose x coordinate is zero and y-coordinate is non-zero will lie on the y-axis.
Answer:
The Red block is the answer
Step-by-step explanation:
Answer: Symmetric property of equality
This is the idea that if x = y, then y = x. We can swap the left and right sides of an equation, and still mean the same thing. The same applies to congruences as well.
