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

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

$f(2) = 5(4)$

$f(2) = 20$

5/2 (7x-15)+x>13/2-3/2

Evgen [1.6K]

5(7x - 15) + 2x ≥ 13x - 3 <em>multiplied both sides by 2 to clear the denominator</em>

35x - 75 + 2x ≥ 13 x - 3 <em>distributed 5 into 7x-15</em>

37x - 75 ≥ 13x - 3 <em>added like terms (35x and 2x)</em>

24x - 75 ≥ -3 <em>subtracted 13x from both sides</em>

24x ≥ 72 <em>added 75 to both sides</em>

x ≥ 3 <em>divided both sides by 24</em>

Answer: x ≥ 3 Notation: [3, ∞)
