The answer is 90° degrees.
Answer:
No
Step-by-step explanation:
When you plug in (2,-2) into the equation, the solution does not equal 4. So the point (2,-2) does not lie on the line.
Answer:
option (b) is correct.
The value of
is 0.
Step-by-step explanation:
Given:
and 
We have to find the value of
Consider the given function
First evaluate value of function f(x) at x = 3 and 1 then substitute it in
.
f(3) = 1 + 3 = 4
f(1) = 1 + 1 = 2
Substitute, we get
Solving further , we get,

Now evaluate
at t = 0 , we get,

Thus, value of
is 0.
Thus, option (b) is correct.
Answer:
Step-by-step explanation:
<u>Given </u>
<u>Simply</u>
<u>Solution</u>
- f(x + h) - f(x - h) =
- (x + h)^2 - 3(x + h) - (x - h)^2 + 3(x - h) =
- x^2 + 2hx + h^2 - 3x - 3h - x^2 + 2hx - h^2 + 3x - 3h =
- (x^2 - x^2) + (2hx + 2hx) - (3x - 3x) + (h^2 - h^2) - (3h + 3h) =
- 4hx - 6h
