For the function f(x)=3xsquared- 2x+5 find f(1) f(-2) and f(a)

Oksanka [162]

$f(x)=3x^2-2x+5\\\\
f(1):\ \ Substitude\ 1 \ as\ x\ into\ function:\\
f(1)=3*1^2-2*1+5=3-2+5=\textbf{6}\\\\
f(-2)\ \ Substitude\ x=-2\\
f(-2)=3*(-2)^2-2*(-2)+5=3*4+4+5=12+4+5=\textbf{21}\\\\
f(a)\ \ substitude\ x=a\\
f(a)=\underline{3a^2-2a+5}$

Let f(x)=x+2 and g(x)=2x+1 .

gogolik [260]

Step-by-step explanation:

Given g(x) = x+2 and f(x) = $2^x+1$

If f(x) = g(x)

⇔ $2^x+1$ = x+2

⇔ $2^x= x +1$

Only x= 1 and x=0 will be satisfy the above equation.

If x= 1, it gives and x=0 gives

$2^1= 1+1$ $2^0=0+1$

⇔2=2 ⇔1=1
