whats the x-intercepts of the graph
y = 42x2 + 28x

  • 12th grade -

    x-intercept: where y is equal to zero.
    therefore:
    0 = 42x^2 + 28x
    0 = x(42x + 28)
    x = 0 ; and
    x = -28/42 = -2/3

    x-int: (0,0) and (-2/3,0)

    so there,, :)

  • 12th grade -

    X-intercept=-7&0
    Y-intercept=0
