Answer:
60
Step-by-step explanation:
Consider the number with digits x, y, z. Its value will be 100z+10y+z. We want the same value when we reverse the digits after subtracting 297.
100x +10y +z -297 = 100z +10y +x
99x -99z = 297 . . . . . subtract 100z+10y+x-297
x -z = 3 . . . . . . . . . . . . divide by 99
The first digit of the number is 3 more than the last digit. There are 60 such numbers. The first digit may be 4..9, and the middle digit may be 0..9.
401, 502, 603, ..., 906; 411, 512, 613, ..., 916, ..., 491, 592, 693, ... 996

Answer:
Y = 3x^x is a graph that has exponential growth while y = 3^-x has exponential decay.
Y = 3x^x (-∞, 0) and (∞, ∞).
Y = 3x^-x (-∞, ∞) and (∞, 0).
Step-by-step explanation:
The infinity symbols were being used to represent the x and y values of each graph. I will call y = 3^x "graph 1" and y = 3^-x "graph 2".
When graph 1 had positive ∞ for its x value, its y value was reaching towards positive ∞. When its x was reaching for negative ∞, its y was going for 0.
For graph 2, however, when its x was reaching for positive ∞, its x was reaching for 0. When its x was reaching for negative ∞, its y was going for positive ∞.
Here's an image of the graphs:
Answer:
y = x2 - 4x + 2 ; y=x²-4
Step-by-step explanation:
Axis of symmetry = - b /2a
y=x²-2
a = 1 ; b = - 2
x = - (-2) / 2(1)
x = 2/2 = 1
y = x2 - 4x + 2
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
y = x2 + 4x + 2
a = 1 ; b = 4
x = - 4 / 2(1)
x = - 4/2 = - 2
y=x²-4
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
