Answer:

-5

Step-by-step explanation:

The equation for slope is:

$Slope=\frac{y_2-y_1}{x_2-x_1}$

We can plug in the given coordinates into the equation:

$Slope=\frac{-2-3}{3-2}=\frac{-5}{1}=-5$

Evaluate the function f(x)=x^2-5x+ 5 at the given values of the independent variable and simplify

11111nata11111 [884]

Step-by-step explanation:

The given function is :

$f(x)=x^2-5x+ 5$

(a) To find f(9), put x = 9 in the above expression.

$f(9)=9^2-5(9)+ 5=41$

(b) To find f(x+7), put x = x+7 in the above expression.

$f(x+7)=(x+7)^2-5(x+7)+ 5\\\\=x^2+14x+49-5x-35+5\\\\=x^2+9x+19$

$f(-x)=(-x)^2-5(-x)+ 5\\\\=x^2+5x+5$

Hence, this is the required solution.
