Question

Let f(x)= -5x+10 then f(-2)=

Simple functions

Answer 1

f(x) = -5 x + 10
Then
f(-2) = -5(-2) + 10
= 10 + 10
= 20

Answer 2

20

Explanation:

Given function is ,

→ f(x) = -5x + 10 .

• For funding it's value at x = (-2). Substitute x = -2 in the given equation .

• Finding f(-2)

→ f(-2) = -5 × -2 + 10

→ f(-2) = 10 + 10

→ f(-2) = 20

• Hence the value of f(-2) is 20
