Answer:

  a = -1

Step-by-step explanation:

The line of symmetry for the parabola given by ...

  y = ax² +bx +c

is

  x = -b/(2a)

Using the given values, we have ...

  -2 = -(-4)/(2a)

Multiplying by -a/2, we get ...

  a = (4/2)(-1/2) = -1

The value of "a" is -1.

Ludmilka [50]

Answer:

(foh)(6) = -29

Step-by-step explanation:

(f o h)(6) is f(h(x)) when x = 6.

We have that:

f(x) = 4x - 1

h(x) = -x-1

f(h(x)) = 4(-x-1) - 1 = -4x - 4 - 1 = -4x - 5

(foh)(6) = -4(6) - 5 = -29

(foh)(6) = -29
