Question

find f(-3)=x^2+3x-4

Answer 1

f(x) = x^2+3x-4


f(-3) = (-3)^2+3(-3)-4


f(-3) = 9+3(-3)-4


f(-3) = 9-9-4


f(-3) = -4

Answer 2

thank you jim..practice problem got me confused with this^ symbol..appreciate it

Answer 3

^ is the exponent symbol


So x^2 means "x squared" and it is written as \[\Large x^2\]

Answer 4

however, how did you come up with the 9+3(-3)-4

Answer 5

(-3)^2 is -3 squared and it is (-3)^2 = (-3)*(-3) = 9


So (-3)^2 = 9
