Question

y= x²-3x-4 put
x= -2
x=-1​

Answer 1

Answer:

we have the equation,

                                 y = x² - 3x - 4

given,           x = -2

                     x = -1​

Step-by-step explanation:

so,

                   taking x = -2

substituting in given equation,

                     y = -2² -3(-2) -4

                     y = 4 + 6 -4

                     y = 6

and,

                    taking x = -1

substituting in given equation,

                     y = -1² -3(-1) -4

                     y = 1 + 3 -4

                     y = 0

Hope it may help you bro :)
