Given f(x) = x − 7 and g(x) = x2 . Find g(f(−1)).

ivann1987 [24]

Answer:

64

Step-by-step explanation:

$g(f(-1))$ can be found by first finding $f(-1)$ then taking that result and putting it into the function $g$ .

$f(-1)$ means we are going to take the expression $x-7$ and evaluate it for $x=-1$ :

$-1-7$

$-8$

So $f(-1)=-8$ .

So we have this so far:

$g(f(-1))=g(-8)=(-8)^2=64$ .

$g(-8)$ was found by replacing $x$ in $x^2$ with $-8$ .

One city's highest temperature during this passed summer was 34 degrees Celsius, a second city's highest temperature over

PtichkaEL [24]

Answer:

$\°F = 93.2$

City 2 has a higher temperature

Step-by-step explanation:

Given

$\°F = (\°C * 9/5) + 32$

$City\ 2 = 97\°F$

Required

Convert 34°C to °F

Substitute 34 for C in the above formula:

$\°F = (34 * 9/5) + 32$

$\°F = 61.2 + 32$

$\°F = 93.2$

<em>Comparing 93.2 to City 2's temperature of 97; we can conclude that city 2 has a higher temperature</em>
