Bill graphed y=3x2+8 and Joy graphed y=3x2+4. What statement describes the difference in the two graphs. Joy’s graph is wider than Bill’s graph
Joy’s graph is half the size of Bill’s graph.
Joy’s graph is located to the left of Bill’s graph.
Joy’s graph is located further down the y-axis than Bill’s graph.

its not b

step-by-step explanation:

it has changed from the width and the height.

step-by-step explanation:

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
