Evaluate the following: f(5) = -4x2 + 5x - 1

Step-by-step explanation:

f(5) = -4x2 + 5x - 1

= -4(5)^2 +5(5) -1

= -4(25) +25 -1

= -100 +25 -1

= -76

f(5)=-8 +5×5-1

f(5)=-8+25-1

f(5)=16

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

$12. that is my answer.
