Fisrst one is just add the functions

(f+g)(x)=f(x)+g(x)=
8x^2+16x+6+x^3-3x^2-9=
(f+g)(x)=x^3+5x^2+16x-3

multiply
ok

f(x)g(x)=(x^3-4x+2)(x^2+2)
just multiply and expand yourself because I don't have my graphing calculator with me right now

Which exponential is equivalent to the logarithmic equation below? log 987 = a

zmey [24]

A logarithmic function without a subscript means that it must be log base 10.

$\log_{10}987=a$

When learning about logarithms, a textbook/teacher provides their students with the following general equations

$\log_yx=z$

$y^z=x$

Hopefully you are familiar with this. Using the equations that I just showed, we can change the equation $\log_{10}987=a$ to $10^a=987$

This would make answer choice C correct.
