which of the following is the graph of f(x) = x2 + 3x − 4?

See Graph

Step-by-step explanation:

Find the Solution for

1x2+3x−4=0

using the Quadratic Formula where

a = 1, b = 3, and c = -4

x=−b±sqrtb^2−4ac/2a

x=−3±sqrt3^2−4(1)(−4/2(1)

x=−3±sqrt9−−16/2

x=−3±sqrt25/2

Simplify the Radical:

x=−3±sqrt5/2

We get x=22x=−82

which becomes

x=1

x=−4

Here is the graph:

what?

step-by-step explanation:

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
