Question

sketch the graph of y=4x^2-4x-3

Answer 1

hey, so same as last time, it's called a "quadratic equation" and takes the form:
\[y = ax ^{2} + bx + c\]

Answer 2

so the key points you want for your sketch ar:
y intercept (when x=0)
x intercepts (when y=0)
turning point (value of "c")

Answer 3

so if you factorise it, you can get your x intercepts:
y = ( 2x + 1) ( 2x - 3
)

Answer 4

therefore your x intercepts occur when y = 0, so
either (2x + 1) = 0 or (2x - 3) = 0
so x = -1/2 or x = 3/2
those are your intercepts (where your graph cuts the x axis)

Answer 5

;)

Answer 6

@ nuh, thats completely incorrect

Answer 7

?no it's right..and the other x intercept is 1

Answer 8

oh

Answer 9

i thought it 4x^3

Answer 10

srry

Answer 11

x intercepts are -0.5 and 1.5

Answer 12

hey whats the quadratic equation?

Answer 13

srry stupid mistake b4..:) read the equation incorrectely lol
