Question

Geniss HELP!!!!!!!!!!!!!!!
What is the axis of symmetry for the function? y = x2 + 3x - 4

y = -2
y = -1.5
x = -2
x = -1.
What are the values of a, b, and c in the function? List them in order with commas, such as 1,-2,3.
y = -2x2 + 5x - 4

Answer 1

i got the first anwser. its x=-1.5

Answer 2

y=x^2+3x-4
y=x^2+3x+9/4-9/4-4
y=(x+3/2)^2-25/4
axis of symmetry is x=-3/2
you should check your options again

2nd question
y=ax^2+bx+c\
y=-2x^2+5x-4
a=-2
b=5
c=-4

Answer 3

you're correct
