Answer:

$\dfrac{3}{2}$

Step-by-step explanation:

If 2x - 3 is a factor of P(x), then 3/2 is a zero of P(x).

$\begin{array}{rcl}2x - 3 & = & 0\\2x & = & 3\\\\x & = & \mathbf{\dfrac{3}{2}}\end{array}\\\\\mathbf{P(\frac{3}{2})} \text{ will equal zero if $(2x-3)$ is a factor of $P(x)$}$

Which function has two x intercepts one at (0,0) and one at (4,0)

marta [7]

Answer:

f(y) = y(y - 4).

Step-by-step explanation:

The function has two x-intercepts of the function are (0,0) and (4,0).

X-intercept means that the y-value will be zero.

Therefore, the function f(y) has two roots, one at y = 0 and another at y = 4.

Hence, the function x = f(y) has two factors (y - 0) and (y - 4)

So, the function is f(y) = (y - 0)(y - 4) = y(y - 4). (Answer)

The table shows the values of a function f(x).

QveST [7]

Answer:

The average rate of change is $=-4$

Step-by-step explanation:

The average rate of change from x=a to x=b of f(x) is given by;

$=\frac{f(b)-f(a)}{b-a}$

We want to find the average rate of change of the function represented in the table from x=-2 to x=2.

$=\frac{f(2)-f(-2)}{2--2}$

From the table f(-2)=25 and f(2)=9

The average rate of change from x=-2 to x=2 is

$=\frac{9-25}{2--2}$

$=\frac{-16}{4}$

$=-4$
