Question

F(x) = —x^2 – 3x
Find f(10)

Answer 1

f(10) = 70

Explanation:

In this question, plug in "10" to "x" and solve.

Solve:

f(10) = -(10)^2 - 3(10)

f(10) = 100 - 3(10)

f(10) = 100 - 30

f(10) = 70

Your final answer would be f(10) = 70

Answer 2

Explanation:

f(x) = —x^2 – 3x

f(10)={-10}²-3×10=100-30=70
