Answer:

$f(-3)=-17$

Step-by-step explanation:

→ Substitute in t = -3 into $f(t)=-2t^{2} +1$

$f(-3)=-2*-3^{2} +1$

→ Simplify

$f(-3)=-2*9 +1$

→ Simplify

$f(-3)=-18 +1$ ⇔ $f(-3)=-17$

What is the equation of the axis of symmetry do the quadratic function f(x) = -(x+4) (x-1)

miv72 [106K]

Answer:

x = -3/2

Step-by-step explanation:

The zeros of the function are the values of x that make the factors zero:

x = -4, x = 1

The axis of symmetry is the vertical line halfway between these zeros.

x = (-4 +1)/2 = -3/2

The equation of the axis of symmetry is x = -3/2.

Which products result in a perfect square trinomial? Check all that apply.

sladkih [1.3K]

The correct answers are:

B=(xy + x)(xy + x) ; C=(2x – 3)(–3 + 2x) ; and E=(4y² + 25)(25 + 4y²)

Explanation:

In order to have a perfect square trinomial, we must multiply two binomials that are exactly the same. For (xy+x)(xy+x), are multiplying two identical binomials.

For (2x-3)(-3+2x), we are multiplying two binomials that are the same but written in a different order. The same is true of (4y² + 25)(25 + 4y²).
