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

(c) To find f(-x), put x = -x in the above expression.

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

Hence, this is the required solution.

Nostrana [21]

Answer:

12 books

Step-by-step explanation:

Since she has $15 and books come in a pack of four for $5, we can divide her money by the cost to see how many she can get ($15/$5) which gets us 3. but we have to remember the books come in a pack of four so we must multiply 3x4=12 books.
