14) what is the graph of the function rule ?

y= |2x|-1​

because the equation contains an absolute value, the shape of the graph would be a v,.

the y intercept is -1, so this would be the lowest point on the graph.

replace x with 1 and solve:

y = 2(1) -1 = 2-1 = 1, so another point would be (1,1) and another point would be (-1,1)   ( absolute value would use both -1 and 1 as the same).

make 3 points on the graph:

(-1,1) (1,1) ans (0,-1) and draw lines through them.

answer:

-13,1

step-by-step explanation:

f(x)= (x+6)^2-49

when we find the zero's   we set f(x) =0

0= (x+6)^2-49

add 49 to each side

49= (x+6)^2-49+49

49= (x+6)^2

take the square root of each side

±sqrt(49) = sqrt((x+6)^2)

±7 = (x+6)

subtract 6 from each side

±7-6 = (x+6-6)

±7-6 = x

7-6 =x               -7-6 =x

1=x                 -13=x
