Question

For the function y = -10x find the matching y-value when x = 3​

Answer 1

-30

Explanation:

y = -10x is a function that can also be represented by f(x) = -10x. We are to evaluate this function at x = 3. To do this, replace both instances of x in this function by 3 and simplify the result:

f(3) = -10(3) = -30

Answer 2

y= -30

Explanation:

THis is because you substitue 3 for X and then multiply -10 and 3 and a negative times a positive is a negative so -10 times 3 is -30
