The answer is 61.

Replace the x in the equation with the nine. F(9) = 8(9) - 11

Now first multiply 8 x 9 which is 72

Now you have F(9) = 72 - 11
Subtract the two numbers.

F(9) = 61

Answer:

Step-by-step explanation:

hi! we can start off by plugging in the number 9 for x in the equation.

f(x)=8x-11)

f(9)= 8(9)-11

= 72-11

=61

hope this helps.

Answer:

16x +8h

Step-by-step explanation:

Use the given function arguments and simplify.

$\dfrac{f(x+h)-f(x)}{h}=\dfrac{8(x+h)^2-8x^2}{h}=\dfrac{8(x^2+2hx+h^2)-8x^2}{h}\\\\=\dfrac{8x^2 +16xh+8h^2-8x^2}{h}=\dfrac{16xh+8h^2}{h}=\boxed{16x +8h}$
