Answer:
Vertex form
Step-by-step explanation:
You convert to vertex form a(x - b)^2 + c . The coordinates of the maxm/minm will be (b, c).
For example find minimum value of x^2 + 5x - 6:-
x^2 + 5x - 6
= (x + 2.5)^2 - 6.25 - 6
= (x + 2.5)^2 - 12.25
The coordinates of minimumm will be (-2.5, -12.25) The values of the minimum of the function is -12.25
The answer is -20 and you solve by putting it in the calculator
Answer:
52
Step-by-step explanation:
If u=(a1i+b1j)=(a1,b1) and v=(a2i+b2j)=(a2,b2), then the dot (scalar) product is:
u.v=(a1,b1).(a2,b2)
a1b1+a2b2
u.v=(8,-7).(3,−4)
(8)(3)+(-7)(−4)
24+28=52
