Answer 1

Answer:

3×2+2×-1

=5+2×-1

=6×-1

=5

Answer 2

Given:-

• Draw the graph of polynomial -3x²+2x-1

Solutions:-

Given Quadratic equations -3x²+2x-1

y = -3x²+2x-1

• put Different values of x , and find different values of y'.

Case 1 :-

X = 1

y = -3 +2-1

y = -2

point (1,-2)

•By this ways find few points ,and plot them in graph .

•As the equation is Quadratic equation , So graph is parabolic in nature.
