Graph a parabola whose intercepts are x=-3 and x=5 and whose minimum value is y =-4
blagie [28]

Answer:

y = 4(x^{2} + 8x + 15) = 4x^{2} + 32x + 60

Step-by-step explanation:

A parabola has the following format:

y = f(x) = ax^{2} + bx + c

If a is positive, it's minium value is:

y_{M} = -\frac{\bigtriangleup}{4a}

In which

\bigtriangleup = b^{2} - 4ac

Factoring:

ax^{2} + bx + c = a(x - x_{1})*(x - x_{2}), in which x_{1} and x_{2} are the intercepts.

In this question:

x_{1} = -5, x_{2} = -3

So

a(x - x_{1})*(x - x_{2}) = a*(x - (-5))*(x - (-3)) = a*(x+5)*(x+3) = a*(x^{2} + 8x + 15)

Suppose a = 1, we have:

x^{2} + 8x + 15

\bigtriangleup = 8^{2} - 4*1*15 = 4

The minimum value will be:

y_{M} = -\frac{4}{4} = -1

We want this minimum value to be -4, which is 4 times the current minimum value, so we need to multiply a by 4. Then

a = 4

And the parabola is:

y = 4(x^{2} + 8x + 15) = 4x^{2} + 32x + 60

zhenek [66]

Answer:

18 boys
