1. If P(x)= x^4+ ax^2+ bx-6 with P(4)=6 and P(2)=0, find the values of a and b.

a = -4, b = -3

Step-by-step explanation:

P(2) = 0

= 4a +2b = -10

P(4) = 6

= 16a + 4b = -52

16a + 4b = -52 - 8a + 4b = -20

= 8a = -32

a = -4

b = -3

55? i think maybe

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
