F(x)=x^2 +8x
f(d-3) basically what we get from this is that the x value is d-3
to find f(d-3) simply plug in d-3 for every x
f(d-3)=(d-3)^2 + 8(d-3)
that would be one form of the answer, but we can also continue multiplying it out
f(d-3)= d^2-6d+9+8d-24
add like terms
f(d-3)=d^2+2d-15

have a nice day and i hope this helps :)

. Find f(3) for the following function
Snowcat [4.5K]

Answer:

\boxed {\boxed {\sf D. \ f(3)= 30}}

Step-by-step explanation:

We are given the function:

f(x)= 3(2)^x+6

We want to find f(3), so we must substitute 3 in for x.

f(3)= 3(2)^3+6

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Solve the exponent first.

  • 2³= 2*2*2= 4*2= 8

f(3)= 3(8)+6

Multiply 8 and 3.

f(3)= 24+6

Add.

f(3)=30

For the function given, f(3) is 30.
