F(x)=3x 2+x<br><br><br> Find f(−5)
Zina [86]

\huge \boxed{\mathfrak{Question} \downarrow}

  • f (x) = 3x² + x
  • Find f (-5).

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

Given,

  • f (x) = 3x² + x

Now, we have to find f (-5). To find this, we just need to substitute -5 in the place of x.

So,

\sf \: f(x) =  {3x}^{2}  + x \\  \\ \sf \: \: Substitute \: x \: as \:  - 5. \\  \\ \sf \:f( - 5) = 3( - 5) ^{2}  + ( - 5) \\ \\  \sf \:Calculate \:  -5 \:  to \:  the \:  power  \: of \:  2 \:  and \:  get \:  25. \\  \\\sf \: 3\times 25+5  \\  \\ \sf \:Multiply \:  3 \:  and \:  25 \:  to \:  get \:  75. \\ \\\sf \:  75+5  \\  \\\sf \:Add \:  75 \:  and \:  5  \: to  \: get  \: 80. \\   \\  =   \boxed{\boxed{ \bf \: 80}}

Answer:

  14x³∛x

Step-by-step explanation:

Factor cubes from under the radical and combine like terms.

  \displaystyle 4\sqrt[3]{x^{10}}+5x^3\sqrt[3]{8x}=4\sqrt[3]{x(x^3)^3}+5x^3\sqrt[3]{x(2^3)}\\\\=4x^3\sqrt[3]{x}+5x^3\cdot2\sqrt[3]{x}=(4+5\cdot2)x^3\sqrt[3]{x}\\\\=\boxed{14x^3\sqrt[3]{x}}

<em>Additional comment</em>

When using an equation editor to create your answers, you need to be careful to make the distinction between the multiplication symbol × and the variable x. Note, too, that exponents generally must be written using the superscript form. x10 and x¹⁰ are not the same thing.
