Question

Given 1x) = 10-2x, find f(7).

Answer 1

Explanation:

Given that,

• f(x) = 10 - 2x

We are asked to calculate the value of f(7).

Substitute the value of x as 7 in the polynomial to find the value of f(7).

→ f(7) = 10 - 2(7)

→ f(7) = 10 - 14

→ f(7) = -4

Therefore, –4 is the required answer.
