Algebra Question (help me check my work)

I was just wondering if I was doing this right...

Evaluate the function when x=3

g(x) = -5(x) + 3

My work:

g(-3) = -5(-3) + 3
g(-3) = 15 + 3
g(-3) = 18

The value of the function is 18

No, your answer is incorrect even though your method is correct. You were asked to evaluate at x = 3, not x = -3:

g(3) = -5(3) + 3
g(3) = -15 + 3
g(3) = -12

However, you did give the correct answer for g(-3) which is what you have in the solution. Did you typo the x=3 part of the question? If so, well done!

that's not right
g(-3)=-5(-3)+3 first i thought x=3 not -3 so wouldn't it be -5(3)+3 which is -15+3 and that equals -12.... the function is -12 not 18
