Answer:

C. 18

Step-by-step explanation:

g(x) = 3x − 3

Let x = 7

g(7) = 3(7) -3

      = 21-3

      = 18

Need help on #30 and 31 thanks!!

30)

\bf \begin{array}{llll}
y=&{{ a}}x^2&{{ +b}}x&{{ +c}}\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\\\\\\
discriminant\implies b^2-4ac=
\begin{cases}
0&\textit{one solution}\\
positive&\textit{two solutions}\\
negative&\textit{no solution}
\end{cases}

31)


a simple case for that would just be, using an equation with an imaginary value, let's do so

\bf \sqrt{-5}=x\implies \sqrt{-1\cdot 5}=x\implies \sqrt{-1}\sqrt{5}=x\implies i\sqrt{5}=x\\\\
-------------------------------\\\\
\textit{so, we'll use that imaginary value then}\\\\
\sqrt{-5}=x\implies -5=x^2\implies 0=x^2+5\implies \boxed{y=x^2+5}

when you get a "solution" or zero with an "i" or an imaginary value, is just a way to say, there's really no solution, the function never touches the x-axis

Consider these four functions. Choose the one which will be the greatest as x → ∞. A) h(x) = 3x B) f(x) = x25 C) g(x) = 5x500 D)
Nikolay [14]
For this case what you should know is that all functions tend to infinity when x tends to infinity.
 However, there are functions that grow faster than others.
 In this case, the function that grows fastest is the one with the highest exponent.
 We have then:
 g (x) = 5x ^ 500
 The exponent of 500 makes the function grow to infinity faster than the other functions.
 Answer:
 C) g (x) = 5x500
