Naddika [18.5K]

Answer:

  • f(x) vertex is a minimum
  • g(x) vertex is a maximum

Step-by-step explanation:

The reasoning is the same in each case: the sign of the coefficient of the squared term indicates the direction the parabola opens. If it opens upward, the vertex is a minimum; if it opens downward, the vertex is a maximum.

f(x) -- the sign of the squared term is positive, so the vertex is a <em>minimum</em>.

g(x) -- the sign of the squared term is negative, so the vertex is a <em>maximum</em>.

Choose the quadratic equation that has a leading coefficient of 8 and solutions -10 and 7/8
Maru [420]

Answer:

f(x)=8x^2+73x-70

Step-by-step explanation:

We are given

zeros as -10 and 7/8

now, we can set up function as

f(x)=a(x-(-10))(x-\frac{7}{8})

now, we are given that

leading coefficient is 8

so, a=8

now, we can plug it

f(x)=8(x-(-10))(x-\frac{7}{8})

now, we can simplify it

f(x)=8\left(x^2+\frac{73x}{8}-\frac{35}{4}\right)

so, we get

f(x)=8x^2+73x-70
