Y = f(x) = 4^x
Find f(x) when x = -1.
Express as a decimal, rounding to the nearest
thousandth.

.25

Step-by-step explanation:

f(x) = 4^x

Let x = -1

f(-1) = 4^-1

The negative in the exponent moves the number from the numerator to the denominator

f(-1) = 1/4

  We want the number in decimal form

      1/4 *25/25 = 25/100 = .25

0.250

Step-by-step explanation:

f(x) = 4^x

x = -1

f(x) = 4^-1

= ¼

= 0.250

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
