Answer:

-124

Step-by-step explanation:

The equation for a discriminant is:

$b^{2} -4ac$

So for

$7x^{2} -4x +5=0$

a = 7 b = - 4 c = 5

Plug values into the equation.

$(-4)^{2} -4(7)(5)$

16 - 140 = -124

Answer: C) f(-4) = 54

GIVE ME A THANKS

Step-by-step explanation:

f(x) = 7 ( 3 - x ) + 5

f(-4) = 7 ( 3 - (-4)) +5

f(-4) = 7 ( 7 ) + 5

f (-4) = 49 + 5

f (-4) = 54
