Which point is an x-intercept of the quadratic function f(x)=(x-4)(x+2)

Mademuasel [1]

Answer:

x = - 2 or x = 4

Step-by-step explanation:

To find the x- intercepts let f(x) = 0, that is

(x - 4)(x + 2) = 0

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 2 = 0 ⇒ x = - 2

The x- intercepts are at x = - 2, x = 4

$\bf r\left[ cos\left( \theta \right)+i\ sin\left( \theta \right) \right]\quad 
\begin{cases}

Find the mean of the rainfall amounts .

anygoal [31]

Answer:

2.25 inches

Step-by-step explanation:

The mean, or the average, or the rainfall amounts, can be found by adding all of the amounts together and dividing by the number of amounts. In this case, $\frac{3+2+1+3}{4}=\frac{9}{4}=2.25$ . Hope this helps!
