Answer:
3
Step-by-step explanation:
Y intercept when x = 0
F(0) = 3 * 4^(0) = 3 * 1 = 3
Answer:
The x intercept is (8,0)
Step-by-step explanation:
To find the x intercept set y = 0 and solve for x
Y=3/4x - 6
0 =3/4x - 6
6 = 3/4x
4/3 *6 = 4/3*3/4x
8 =x
The x intercept is (8,0)
Answer:
6 2/4 is a mixed fraction and 1/6 is not.

Answer:
<h2>x =
-2+i√5 and -2i-√5</h2>
Step-by-step explanation:
The general form of a quadratic equation is ax²+bx+c = 0
Given the quadratic equation x²+4x+9=0 in its standard form, on comparing with the general equation we can get the value of the constant a, b and c as shown;
ax² = x²
a = 1
bx = 4x
b = 4
c = 9
The quadratic formula is given as x = -b±√(b²-4ac)/2a
Substituting the constant;
x = -4±√(4²-4(1)(9))/2(1)
x = -4 ±√(16-36)/2
x = -4±√-20/2
x = -4±(√-1*√20)/2
Note that √-1 = i
x = -4±(i√4*5)/2
x = (-4±i2√5)/2
x = -4/2±i2√5/2
x = -2±i√5
The solution to the quadratic equation are -2+i√5 and -2i-√5
