M(x) = 2x^2 + 6x - 7.......find m(3) by subbing in 3 for every x
m(3) = 2(3^2) + 6(3) - 7
m(3) = 2(9) + 18 - 7
m(3) = 18 + 18 - 7
m(3) = 29 <==

I need answers for all! thank you will mark brainlist!! please help me i’m begging you &lt;3
Darina [25.2K]

Step-by-step explanation:

y = 2/5 x - 9/5

when x = -1,

the value of y = 2/5(-1) - 9/5

= -2/5 - 9/5 = -11/5

when x = 0

=> y = 2/5(0) -9/5

= 0-9/5 = -9/5

when x=1

=> y = 2/5(1) - 9/5

= 2/5 - 9/5 = 7/5
