If the graph is reflected across the y-axis, what will be the equation of the new graph? a) y=-3^-x+1
b) y=3^-x+1
c) y=-3^x-1
d) y=-3^x+1

Step-by-step explanation:

we are given a exponential function

we want to figure out the equation of the new graph reflected across the y-axis

remember that,

let y be so,

hence,

the equation of the new graph

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )
