Given that f(x) = 10x + 45, find f(7)
sattari [20]

Answer:

\boxed{\bf f(x) = 115}

Step-by-step explanation:

<u>Given polynomial </u><u>function </u>:-

f(x) = 10x +  45

<u>To </u><u>find</u> :-

\sf \: f(7)

<u>Solution:-</u>

\sf \implies \: f(x) = 10x + 45

Here, the value of x is 7(given).

So, <u>Substitute the value of x on the RHS and </u><u>on </u><u>LHS </u>:-

\sf \implies{f}(“7”) = 10(“7”) + 45

Simplify the RHS:-

<u>Multiply 10 and 7 :-</u>

\sf \implies{f}(7) = 10 \times 7 + 45

\sf \implies{f}(7) = 70 + 45

<u>Add 70 and 45 :-</u>

\sf \implies{f}(7) = 115

We're done!

Hence, the value of f(7) would be,

\sf \implies{f}(7) = 115

\rule{225pt}{2pt}

I hope this helps!

We are given with a quadratic equation which represents a Parabola , we need to find the vertex of the parabola , But let's recall that , For any quadratic equation of the form ax² + bx + c = 0 , the vertex of the parabola is given by ;

{\quad \qquad \boxed{\bf{Vertex = \left(\dfrac{-b}{2a},\dfrac{-D}{4a}\right)}}}

Where , D = b² - 4ac (Discriminant)

Now , On comparing the given equation with ax² + bx + c , we have

⇢⇢⇢ <em><u>a = 1 , b = - 10 , c = 2</u></em><em><u>7</u></em>

Now , Calculating D ;

{:\implies \quad \sf D=(-10)^{2}-4\times 1\times 27}

{:\implies \quad \sf D=100-108}

{:\implies \quad \bf \therefore \quad D=-8}

Now , Calculating the vertex ;

{:\implies \quad \sf Vertex =\bigg\{\dfrac{-(-10)}{2\times 1},\dfrac{-(-8)}{4\times 1}\bigg\}}

{:\implies \quad \sf Vertex = \left(\dfrac{10}{2},\dfrac{8}{2}\right)}

{:\implies \quad \bf \therefore \quad Vertex = (5,2)}

Hence , The vertex of the parabola is at (5,2)

Note :- As the Discriminant < 0 . So , the equation will have imaginary roots .

Refer to the attachment for the graph as well .
