Given f(x) = 52x, evaluate f-1), f(o), and K2).<br><br> 01/25, 1, 625

lbvjy [14]

Answer:

$f(-1) = \frac{5}{2}$

$f(0) = 5$

$f(2) = 20$

Step-by-step explanation:

Given

$f(x) = 5(2^x)$

Required

Determine f(-1); f(0) and f(2)

Solving f(-1)

In this case, we simply take x as;

$x = -1$

Substitute -1 for x in $f(x) = 5(2^x)$

$f(-1) = 5(2^{-1})$

Apply law of indices

$f(-1) = 5 * \frac{1}{2}$

$f(-1) = \frac{5}{2}$

Solving f(0)

In this case, we simply take x as;

$x = 0$

Substitute 0 for x in $f(x) = 5(2^x)$

$f(0) = 5(2^0)$

$f(0) = 5(1)$

$f(0) = 5$

Solving f(2)

In this case, we simply take x as;

$x = 2$

Substitute 2 for x in $f(x) = 5(2^x)$

$f(2) = 5(2^2)$

$f(2) = 5(4)$

$f(2) = 20$

Ahmed wrote an expression as 12x + 24, find all the equivalent expressions using the distributive property.

xeze [42]

Answer:

$12x + 24 = 2(6x + 12)$

$12x + 24 = 3(4x + 8)$

$12x + 24 = 4(3x + 6)$

$12x + 24 = 6(2x + 4)$

$12x + 24 = 12(x + 2)$

Step-by-step explanation:

Given

$12x + 24$

Required

Equivalent expressions

No option were given; So, I will list out some possible equivalent expressions.

Using distributive property:

$AB + AC = A*(B + C)$

So, we have:

$12x + 24 = 2*6x + 2 * 12$

$12x + 24 = 2(6x + 12)$ ----- (1)

Another:

$12x + 24 = 3*4x + 3 * 8$

$12x + 24 = 3(4x + 8)$

Another:

$12x + 24 = 4*3x + 4*6$

$12x + 24 = 4(3x + 6)$

Another:

$12x + 24 = 6*2x + 6*4$

$12x + 24 = 6(2x + 4)$

Another:

$12x + 24 = 12*x + 12*2$

$12x + 24 = 12(x + 2)$
