Answer:

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

Explanation:

Given polynomial function :-

f(x) = 10x + 45

To find :-

$\sf \: f(7)$

Solution:-

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

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

So, Substitute the value of x on the RHS and on LHS :-

$\sf \implies{f}(“7”) = 10(“7”) + 45$

Simplify the RHS:-

Multiply 10 and 7 :-

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

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

Add 70 and 45 :-

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

We're done!

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

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

$\rule{225pt}{2pt}$

I hope this helps!
