Let f(x) = -2x - 7 and g(x) = -4x + 6. Find (fxg)(-5). a. -59 b. 3 c. 26 d. -6

DedPeter [7]

Answer:

Step-by-step explanation:

The given functions are:

$f(x) = - 2x - 7$

and

$g(x) = - 4x + 6$

$(f \times g)(x) = f(x) \times g(x)$

$(f \times g)(x) = ( - 2x - 7)( - 4x + 6)$

When we plug in x=-5, we get:

$(f \times g)( - 5) = ( - 4 \times - 5 + 6)( - 2 \times - 5 - 7)$

$(f \times g)( - 5) = ( 20 + 6)( 10 - 7)$

$(f \times g)(5) = ( 26)( 3) =7 8$

The graph of which function has an axis of symmetry at x = 3? f(x) = x2 3x 1 or f(x) = x2 – 3x – 3 or f(x) = x2 6x 3 or f(x) = x

Wittaler [7]

For
ax^2+bx+c
the axis of symmetry is -b/2a

first one
-3/2=3, nope

2nd one
3/2=3? nope

3rd one
-6/2=3? nope

fourth
6/2=3? yes
answer is last one or
f(x)=x^2-6x-1
