Its the shape of graph. Linear are straight lines. Quadratics have a certain shape. Look up quadratic function on google.
Answer:
![-7+5[(-5)^2+(-32)]=-42](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-42)
Step-by-step explanation:
First solve the sums that are within the parentheses.
Remember that if the numbers have equal signs then they are added and the same sign is placed.
If the numbers have different signs they are subtracted and the sign of the major is placed
So:
![-3-2=-5](https://tex.z-dn.net/?f=-3-2%3D-5)
![2^3 -40 = 8-40=-32](https://tex.z-dn.net/?f=2%5E3%20-40%20%3D%208-40%3D-32)
Then we have the following expression:
![-7+5[(-5)^2+(-32)]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D)
Remember that by multiplying signs you get:
(+) * (+) = +
(-) * (-) = +
(+) * (-) = -
(-) * (+) = -
Then:
![-7+5[(-5)^2+(-32)]=-7+5[(-5)*(-5) -32]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7%2B5%5B%28-5%29%2A%28-5%29%20-32%5D)
![-7+5[(-5)^2+(-32)]=-7+5[25 -32]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7%2B5%5B25%20-32%5D)
![-7+5[(-5)^2+(-32)]=-7+5[-7]](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7%2B5%5B-7%5D)
![-7+5[(-5)^2+(-32)]=-7-35](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-7-35)
![-7+5[(-5)^2+(-32)]=-42](https://tex.z-dn.net/?f=-7%2B5%5B%28-5%29%5E2%2B%28-32%29%5D%3D-42)
Answer:
