F(x) = 2x^2 4, find f(3)
a. 22
b. 16
c. -0.5
d. 40

A. 22

Step-by-step explanation:

f(x) = 2x^2 + 4

f(3) = 2(3)^2 + 4

Do the exponent first according to PEMDAS

2(9) + 4

Multiply

18 + 4 = 22

I hope this helped!

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
