Answer:
B. vertical stretch by 4, translate left by 5
Step-by-step explanation:
When the output of a function is multiplied by a factor, its graph is stretched vertically by that factor. So 4√x stretches √x vertically by a factor of 4. This knowledge by itself lets you select the correct answer choice, B.
When a value is subtracted from the independent variable, the graph is moved (translated) to the right by that amount. Here -5 is subtracted to get √(x+5) from √x. So the graph is translated to the left by 5 units (the opposite of right).
Taken together, these transformations stretch the function vertically by a factor of 4 and translate it left 5 units.
Answer:
a) one solution, x=3
b) see below
Step-by-step explanation:
2x+3=4x-3
2x=6
x can only be=3
The answer is Value equals 1583.36 cubic feet
X^2 + y^2 = 9 . . . . . . . . circle
y = x + 3 . . . . . . . (linear graph)
They intersect at (-3, 0) and (0, 3)
