Question

Eualuatef(x)=2x²-3x+4 at x=7

Answer 1

Answer:

81

Step-by-step explanation:

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

f(7)=2(7*7)-3(7)+4

=2(49)-21+4

=98-17=81

Answer 2

The value f(x) at x = 7 is 81

Given :

The function f(x) = 2x² - 3x + 4

To find :

The value of f(x) at x = 7

Solution :

Step 1 of 2 :

Write down the given function

Here the given function is

f(x) = 2x² - 3x + 4

Step 2 of 2 :

Find the value at x = 7

The value of f(x) at x = 7

= f(7)

= 2 × 7² - ( 3 × 7 ) + 4

= 98 - 21 + 4

= 81
