Consider the quadratic function f(x) = x2 – 8x – 4. what is the value of the leading coefficient? –8 –4 0 1

1 is leading coefficient. last option is correct

Explanation:

We have been given the quadratic function

We know that leading coefficient is the coefficient of the variable having highest exponent.

So, in order to state the leading coefficient we first of all find the highest exponent of the given function.

Clearly, the given function is quadratic and hence, the highest exponent is 2.

The coefficient of the variable of highest exponent is 1.

Therefore the leading coefficient is 1. last option is correct

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

answer: x=3 and y=4
