Answer:

70 is answer

Step-by-step explanation:

Given that a function in x is

$f(x) = 5x^2$

we have to find f'(7)

we know by derivative rule derivative of a function is

$f'(x) = lim_({h-->0}) \frac{f(x+h)-f(x)}{h}$

For finding out at 7 we replace x by 7

$f'(7) = lim_({h-->0}) \frac{f(7+h)-f(7)}{h}$

= $lim\frac{5(7+h)^2-5*7^2}{h} \\= lim \frac{10h*7+h^2}{h} \\= 70+h = 70$

So f'(7) = 70

answer is 70
