1.28 ÷ 4 = 0.32
But the "models" make little or no sense. I can see the three bars and two dots representing the digits 3 and 2, but that is the only image I see, repeated three times. It also shows no reference to the decimal place, so I would say there is no real representation of it all.

Given function:
f(x) = 4x² + 8x - 5 Part AThe x-intercept is the point(s) with y = 0
4x² + 8x - 5 = 04x² + 8x + 4 = 9(2x + 2)² = 92x = -2 ± 3x₁ = -2.5x₂ = 0.5Part BThe leading coefficient is positive. It mean the graph opens up. It in turn means the vertex is the lowest point.
The vertex is defined by:
x = -b/2a, which is x = -8/(2*4) = -1f(-1) = 4(-1)² + 8(-1) - 5 = -9Part CPlot the vertex (-1, -9), x-intercepts (0.5, 0) and (-2.5, 0) and connect the points considering the graph opens up. You may need to add more points to the graph if need more accurate graph.
